The maser goes mainstream: Diamond microwave lasers
Vložit
- čas přidán 14. 08. 2024
- You may have heard of lasers, but what about their older brother - masers. Invented in the 1950s, masers use microwaves instead of light, but they were somewhat eclipsed by the much more practical laser. More than half a century later, researchers are demonstrating a new kind of maser, made using diamond. Nature reporter Elizabeth Gibney went to see it in action.

music is unnecessary
The music made it less dry and boring as this is for entertainment not for a boring classroom instructional video.
Not as unnecessary as your comment.
Well, I enjoyed it but then I don't have a stick up my ass or clutching some damn pearls OR trolling.
Music in general is fine, but this particular track is utter garbage.
Stephen Kramer very much agree. If I wanted to take molly and chew on a pacifier I’d go to a music festival on 4/20 weekend called “Backwoods”. The line up is gonna be siiiiiiiick.
Nature consistently produces the absolute best science videos on CZcams. Keep up the fantastic work Noah, Elizabeth, and Lizzy!

also look into "electric universe" and the "thunderbolts project"
Surprising this discovery was released. A powerful maser would make an unstoppable weapon. Unlike lasers you cannot just put a mirror coating on things to reflect it. It does not have to burn through anything to destroy the electronics inside. You may have just ended aviation as a war tool. Military satellites may also be history now. I guess it is back to horses and cannons.
Not quite, the microwaves are so low frequency/large wavelength that the beam cannot be very concentrated. Moreover, you can just put things in a Faraday cage.
Nos anos 60 aprendi que MASER seria como o LASER gerando ondas de ultra-som poderosas, e não ondas de luz. O princípio seria a eletrostricção, que é a oposição de 2 campos eletromagnéticos;
Now if they could just get around to completing a Gazer, Raser, Dazer, X-Rayser, and Sprayser you could stack them and still have a hand free.
definitely use a more subtle background music for this specific narrators voice, just a suggestion. Awesome video very interesting
How can anybody learn anything if all they pay attention to is the music? I watched it fine and only came to the comments to see if anyone could think of any applications. No chance finding an intelligent comment. Why did I bother?
Aaron Lowe I wasn't saying anything negative, it's just that the narrators voice sounds pretty captivating so I'm really trying to pay attention to what she is saying and visualize it in my head, but that twisting synth noise is very distracting, only reason I leave comments like that is for constructive criticism, I find the video very interesting and I hope they read the comment so next time they just don't use any music at all or use something very subtle because it is a bit distracting. Not everybody is as talented as others with pairing up background music with different voices, her voice needs a much more subtle drone or even a tension bed, honestly was not trying to be mean.
You can understand that when someone comes to the comments and half are about the music while the other half are about tits it can come across as juvenile. I've lost count of the number of times I've suggested to people that they adjust the volume control to get the perfect balance.
What about the ending where Einstein seems to be tripping balls? You know, opening the third eye and stuff?
I agree. The content is interesting but the videomaking is completely wrong imo. This is supposed to be a science channel but videos are made like 'extreme top 5' or channel like that
Continuous MASERs can be used for micro etching like for CPU dies among many other manufacturing environments. Imaging how efficient energy transmission can be with this!
That would be wonderful.
5:55 I learned something new: Albert Einstein could shoot lasers directly from his brain.
But only once!
I seriously doubt that those people were the first to get the idea of using diamonds. They were simply the first to use synthetic diamonds. The first working laser was a ruby laser, don't tell me that no one was thinking about diamonds in masers before.
The photon is pulled out of the electron by the matching frequency of the passing photon (tuning forks). The electron is mediated into a lower state.
The coherent waves of the laser are made extra coherent by the crystalline lattice of the diamond.
If the electrons were in the radio waves spectrum, would it be a RASER?
MusiCanines - The Musical Dogs Electrons aren't in the emission, it is the change in energy of electrons that causes the emission of a photon
MASER produces radio wave.
You mean photons as will pointed out but yes, the term RASER, UVASER, XASER and IRASER were all used for a (very) short period of time just after the laser was invented until I guess someone realized that everyone (physicists) were already colloquially using the word light to describe all forms of electromagnetic radiation anyway so they just dropped all the pointless prefixes and called almost everything a laser. Only the maser retains its name distinction today.
Only if the electrons are in China.
+10mintwo There is no such thing as photons.
now i need a microwave flashlight to burn somebody's lunch and they wont see it hehehe
@@metanumia invisible laser gun
That music was too distracting.
It's like 90s video-game music rofl
Andre Cook *Yes, just a bit.*
it was rave music... they were doing a light show with mazers

I didn't even notice it
So supervillains stealing the worlds largest diamond for their destructobeam, is not _actually_ that far off?
Great, you just invented a death raygun.
I’ll take two please
"The precisely calibrated magnetic field " makes me think that perhaps this is the perfect instrument to measure "Gravity" waves or the Ether via the Michelson-Morley experiment . Where can we get more information on this experiment?
Just curious....Who's watching this after what has happened in Maui Hawaii??? R.I.P to all those that have lost their lives to this horrible act against the people! All my love and prayers to the families and to the community
It is interesting to know how this works, but wouldn't it have been obvious before? Where the NV center changes its spin based on microwaves, it would make sense that microwaves would also be released with the proper conditions.
Sure sure... But can it run Crysis?
HAHAHAHAH good one :)
there are different tools available for running computer games.
@combrastudios oh dear, that was a great joke...
Crysis jokes in 2018
Put it to the test!!
L.A.S.E.R. - Light Amplification by Stimulated Emission of Radiation
M.A.S.E.R. - Microwave Amplification by Stimulated Emission of Radiation?
yes
That's exactly what the guy said in the video.
I was half expecting to see Ron Jeremy make a cameo appearance with this ...music, if you can call it that!
Certain spectral frequencies of MASERs also can excite the inter-cranial cavity, as well as resonating the intraneural fibroids in the brain, which can be used for good (take me for example)...
or bad - imagine a maser that can fry your brain in a split second without being visible like laser. It seems the maser using a diamond could potentially be made into a gadget small enough to basically replace a gun, that could look like a wand of sorts.
It would have been nice to know the frequency.
I, along with many other viewers, would like to know what is so fascinating about masers that we have this research being conducted on how to make a maser function at room temperature. What job is so needed that only the maser will do it? Someone with actual knowledge on this topic please inform us. Thanks.
Maser wont require Optical cables, as Radio waves can penetrate walls!
Just directly beam the data!
They have a lot of uses, better radar, better radio telescope for satellites, better medical imaging that might be done in seconds instead of minutes, better detection of diseases or drugs in a body and a whole lot of other stuff I can't even think of.
They did not make the first room temperature maser. It was done in 2012.
Astounding video !! Great work...
"I had to go for a walk, calm down a little" what a lovely guy
in other words "i had to go take a shit."
But where does the flux capacitor go?
Einstein may have produced some underlying theory but the courage to attempt a maser goes to an amazing human being named Dr. Charles Townes. He had the faith that a maser could be made against considerable opposition of opinion.
Any new information on this? Has scaling been done?
"photocopier for photons" . Giggled.
what is with that garbage background music?????

This sounds like what AT&T was using for multi channel long distance telephone links in the 1960’s and 1970’s. I saw a demonstration of it. The called it a MASER then too.
Hmmm, I wouldn't be at all surprised if masers are what's behind these mysterious sonic attacks we've heard about over the past couple years.
Good catch - was thinking exactly the same. It can be used as a very sophisticated and somewhat hard to detect weapon. Unless you have detectors ready, you won't even know what hit you as, unlike lasers, microwaves are invisible to humans.
I read that the Great Pyramid at Giza may be a maser, so can you use water, granite/crystals and sound for your maser as well?
Lmao
so what do masers do that lasers dont?
I hope they all have their proper laser/maser licenses.
Right now at my house in white bear lake, Minnesota..I have masers surrounding my house..swarming it
And they fight giant monsters.
Why there's no maser-based guns/weapons in sci-fi movies/tv shows like laser and only in Godzilla films ?
what practical applications could a maser be used for if the beam were strong enough ?
would it be used for the same applications as lasers are ?
Maser wont require Optical cables, as Radio waves can penterate walls!
Just directly beam the data!
Better radar, better radio telescope for satellites, better medical imaging that might be done in seconds instead of minutes, better detection of diseases or drugs in a body, etc.
If the technology matures and efficiency goes up we could expect maser based etching to be more efficient than laser based etching. I'd assume cpu die etching would be a wonderful application. And as was mentioned by a previous user the fact that masers are non optical means there is a possibility for non direct transmission. However it should be noted that microwaves are a high frequency wave unlike radio waves which are low frequency, its unlikely masers could pass through solid objects.
Interesting topic, but the music is really disturbing, makes it hard to watch
1:15 dat stutter before he said "stimulated emmision" lmao
There's no stutter there. A slight pause but no stutter.
Diamonds are a scientist's best friend.
I like to think Einstein really had a laser shooting out of his forehead
I WANT SHARKS WITH FRICKIN MASER BEAMS!!!
What about observing known GW with a maser telescope? Robust PCA and generate a vector approximation with known values.
you forgotten to show coherent microwave emitted from diamond. Otherwise, it was nice to see that Imperial College learnt to shine a laser on a piece of material
Babysteps....babysteps...
They've learned the laser pointer, let's not get ahead of ourselves until we see a proper bench - Which I'm pretty surprised didn't show up in the video.
Andrey Kaplan It's a bloody promo video, they're just demonstrating the concept. Go read their paper if you want the actual details.
That's a satisfying bootiful explanation....
Now build a maser cannon like in war of the gargantuas
Who else is here after watching Praveen Mohan's latest video on Vajras?
I remember reading about ruby masers in a book, Contact IIRC.
What does this mean for self-driving cars?
Will this work like LIDAR only also in the rain & snow?
Now that would be a breakthrough.
Can we place a satellite in a stationary orbit of the moon and have a maser array that is pointed at the satellite.
Super cool Young Scientists..Inspiring..Respect....
The laser goes skrrrraa
voice audio too soft
Volume control.
Deep DEEP space signal and image work can be done with this to discover the very weakest of signals such as getting an image of a planet orbiting a distant star, perhaps?
Jesus, the comments on this video are *hilarious*. It's like 80% people who have wildly insane misunderstandings of basic science or are convinced they've stumbled onto a basic and obvious problem that wasn't noticed by peer reviewers. There's someone speculating that these *microwaves* were the source of the (imaginary) sonic weapons attacks. There's someone acting as if the jury's still out on relativity. And these are people who voluntarily watch videos about science in their free time.
Lol, reading these comments make me believe, that majority of people, that wrote them, were drunk or high af while making them.
If we excite a Maser with a Diamond created with Isotopes wouldn't that produce far more power? And what about doing that exact same thing but with Man Made Ruby's?
If Arnie was there threatening to destroying stuff... would it be an Eraser? 😂
Imagine a WiFi laser...
What's the advantage of a maser vs a laser?
Not to mention the stone the laser goes through must be faceted in a certain way, if you see this guy give him a slap with your black hand for me cause I know I will
I did think a satellite in elliptical orbit of the earth(if stationary orbit behind the moon is impossible) would be good for observing the gravetarional lensing of the sun a few times per month. That would be shorter viewing time, though.
How are masers better than lasers?
Microwaves pass through many things unlike light.
Communications!
were using microwaves to communicate now. that's not the question.
"how are masers better than lasers?" idk and not sure anyone else does rn. they are just different colors. you're question maybe should be "how are masers better than regular microwaves?" and that would depend on what you are trying to do. it's probably not going to be earth bound communications. I guess one day it could be but it just seams silly. basically you would need to constantly track each other's exact location near perfectly and then gimbal your antennas near perfectly otherwise you loose signal. all to save on a little power. maybe for deep space missions, maybe, and we would conjoin those with lasers, and lasers alone would work.
masers are just like lasers only a color of light you can't see. kinda like your tv remote is a flashlight, only its a flashlight that you cant see. saying "masers! masers! think of the communication!" is like saying that you want a tv remote that you have to point in just the exact right spot on the tv otherwise it wont work but the battery in it lasts longer. it's silly bc nobody wants it and energy consumption isn't a real issue.
tards blocking energy production is the issue. I dont see masers helping the fact that a lot of peoples brains are full of garbage disinformation.
John Doe some times less is more
I'M NOT READING ALL THIS
no one asked you to omar. read less if you feel like it.
What do you mean? He asked how masers are better than lasers. It is a simple question to answer, and I did so. Microwaves pass far better through objects. That is how they are better, are they more complicated to use right now? Yes, of course. However, that one fact I stated answers the question already.
One thing I stated afterwards was that this allows for improved communications. Clearly you have no idea how current microwave communication methods work, they are not like lasers. The farthest in focusing them we usually go is by using dish's to transmit internet packets to businesses.
Why so nervous? is she hard to talk to?
Right, you made a maser, what the heck is it for?
Are microwaves longer or shorter than light? How powerful is the maser you demonstrated? In the demo you said the trigger frequency had to match the output frequency. In your demo the freqencies were quite different. What gives?
longer, they are below visible light by a few orders of magnitude - microwaves are in Ghz while visible light is in Thz range.
Let's just be honest here. Carbon is the most amazing element. Diamonds, carbon nanotubes, graphene, and "carbon based lifeforms" as the saying goes.
Were is microwaves test?
It just shows green in and a pick out..... That not a laser, just colure shift.
I wanted to try with optical data
If light is an electro magnetic wave ... what is waving ?
no the music doesn't go away, bummer
The Universe is a Crystal Core Quantum Computer and Microwaves are the magic frequency to manipulate the Malleability that is inherent within... OMG!!!
we have enough lasers
They have technology that could help humanity but they won't reveal it cause of greed. Shame .......????????
I wonder how the military could use this?
5 years ago.
So I probably won't be using a MASER to reheat my mug of cold tea. 😔
Cool. Time for some multi-gigabit FSO comms!
That's a masing... but I'm not buying my music and movie collection again.
Don't tell the bobbies, they'll MASER you with it. But seriously its an aMAZERing discovery.
I guess somethings get lost in the waves and particle spectrum have to get revived to make them interesting again. Laser gotten so much better within a broad spectrum of producing specific photons.
Where a maser just apply's as an resonator which is more interesting then to have it provide a stimulated emission of some sort. But no the hard walk among scientist is just use that one particular usage where its described to function for, Isn't it Cern. Isn't it Iter, Isn't it Tokamak.
Aren’t microwaves a form of light? Last I checked they have a frequency of 300 MHz to 300GHz
300 MHz is uhf high, usually microwaves are considered to start at 1000 MHz or one GHz and go up to 1000 GHz (1 THz)
Light, or the part of the electromagnetic spectrum visible to humans is past microwaves, past infrared, generally 380 to 740 nanometers or 4 to 8X10¹⁴ Hz. And there light sits, on the far end of the DC to daylight scale, but past it comes uv to x-rays to gamma rays to cosmic waves, and that's some high energy stuff!!!
Try compressing uranium 235 and carbon into a "black diamond " ...... I think it would enhance the power
TO QUOTE WANDA SYKES
"THESE PEOPLE ARE SO SMART, THEY ARE USELESS"
i always assumed lasers could be in any part of the spectrum.
Not just visible light.
Yes, but when it's not visible it's called other things, like microwaves...
The shaking camera and "music" was a bit much. Great subject though.
Microwaves are light just as radio ultra violet x ray and gamma.
yeah I was going to watch it, the music is way too annoying. It's like canned laughter on a sit-com, I won't watch those because of that. Maybe I'll come back if the music goes away.
Where else will masers be used next?
Almost certainly weapons.
Oh yes, and power transmission. But weapons for sure. One application is simply focusing a maser on a target, like a missile, in order to heat it up. The coherence of the microwaves cause A/C electrical current to flow in conductive materials, this is will cause resistance heating. But since it is coherent, only high resistance metals will heat up quickly. Low resistance metals will turn into antennas that broadcast a microwave signal, so some % of the microwaves will be reflected instead of turned into heat at the target.
Another possibility:
If you ionize the air with a UV laser it becomes opaque to microwaves but transparent to UV, as well as electrically conductive. If you target this plasma with microwaves it would rapidly heat and continue to ionize the surrounding air, engulfing any volume of air you could focus the maser onto in high energy plasma.
@@scienceminded I wonder if (like LASERS) MASERS would possess both temporal and spacial coherence.
@@BaddaBigBoom In fact that is exactly what happens. MASERS by definition have both spatial and temporal coherence. That is to say, both the phase and the frequency of some population of photons emitted are constant. The closer that the phase of a group of photons is to 0 degrees difference from one another, the more of a pure sine wave forms with amplitude equal to the sum of the individual photons that make it up.
If your lasing medium doesn't cause the population of electrons to emit light in phase, but at the same frequency, then you have made a monochromatic laser (single frequency), with poor spatial coherence but excellent temporal coherence.
Anything other than 0 degree phase difference will result in destructive interference in some places, and constructive interference in others, making for pulses of energy and 'dark solitons' or pulses of darkness that are not necessarily at the frequency of the individual photons.
I had the understanding that a maser is a "matter laser" that emitted particles
Well, it's not !
What about using x-ray, UV or Gamma waves to do this?
just dont shine them in my eyes unless you want too get bitten
This is probably what hurt the Cuban embassy workers.
Besides communism.
Skippy would be proud.
4:14 why she is using cheap green laser by knowing the fact it use very poor ir cut filter 🙄
what is the use for this over a normal laser?
Google it.
Right, you made a maser, what the heck is it for? Don't tell me to Google it when you can mention it.
New telescopes (i.e. a better understanding/updated and improved version of the cosmic microwave background - potentially the single greatest available resource for big bang scientists at the moment.); new experimental capabilities for analyzing baryon-boson interactions, better microwaves (lol), etc...
Pump it up, you gotta pump it up
