Just want to chime in that pulsed lasers don't just exist because of electrical restrictions, they have many interesting properties, uses, and advantages compared to CW lasers. For example, in laser cutting, a sufficiently fast pulsed laser will dump energy into the material so quickly that the heat does not have time to dissipate before the material vaporizes, giving a much cleaner cut.
CW lasers don't also do that?
@@marca9955 Lower peak output, so they heat up the material slower at the exact point of burn, or they have to be more powerful to achieve same output. They dump more energy into the material overall, but we don't want that, we want to burn exactly what we want to burn and touch nothing else. So the pulsed laser is more controlled, the CW is less, but allows faster cutting. There are pros and cons to each. Also depending on material, the pulsed laser also can allow the vaporized material to clear the cut before the laser dumps more heat into it, while the CW will dump some of the energy into the vapor cloud, resulting in absorption and scattering.
while I understand what you're saying, technically, the guys' statement is correct. If you had a cw laser with the same average power as a pulsed laser's peak power, than you would achieve the same thing if you gated the cw laser accordingly (which might be impossible electrically for high loads if it's >xMHz). Anyways, a 1MHz 1ns pulsed laser with 1kW average power has 1MW peak power. If you use that to process at 1m/s than you could achieve similar results if you processed using a 1MW cw laser at 1000m/s , just get a fast polygon scanner :P - well, obviously I'm aware of the thermal limitations in optical components and also power-density limits during most material processes.
If you want higher peak powers/fluences however, you're out of luck. Imagine a 100kHz 1ps laser with 200W average power - one can get those off-the shelf too. That's 2GW peak power. Now we need a small rocket to match the power output, or two standard sized nuclear power plants... Not gonna happen.
--> Pulsed lasers will win!
regards - a laser physicist.
The only comment he liked was this one.
It also allows time for some of the smoke to clear out of the way so as to not block the laser. A CW laser has to shine through the smoke generated while a pulsed one can be timed to limit the smoke interaction thus imparting more energy into the target
The strongest laser is your ceiling light at 6 am when your dad wakes you up

Just want to be clear, there’s a huge difference between FDA approved and FDA cleared. I have a degree in biomedical engineering, and it takes very little effort to get a medical device “FDA cleared”. It takes exponentially more to get something FDA Approved, which is what really means something.

It's crazy how some dry pellets and some fluid can produce such brilliant, bright light.

The chemical storage was only a small factor for the decommissioning of the Boeing YAL-1. Testing showed that the atmosphere had too much of an affect on the powerful laser, causing it to lose a significant amount of energy due to heat and light scattering. While they initially billeted the laser as being able to operate from hundreds of kilometers away from its target, after testing it was shown the actual effective range was not nearly as long as they had hoped. They would basically have to fly into hostile airspace to get a chance to shoot their targets long enough to destroy them, which defeated the purpose of a standoff ABMS.
As of yet, there is no effective way to destroy an ICBM during its first phase of the launch because they are extremely fast and positioned very far inland in most nations that have them. Most efforts nowadays are into stopping them during the second phase (the ~15 minutes while they are freefalling in space) or the third phase (the ~2 minutes of terminal velocity before airburst of the warhead). As of right now, the big huge chemical laser of the YAL-1 will probably remain unused, unless we decide to put those things in space, lol
Yes, it struck me as odd that an organisation that routinely carries massive amounts of explosives should shy away from a few (admittedly reactive) chemicals.
Bring on the Tesla Death Ray!
What with the lol
I don't think it would operate in space either. Every laser has a divergence, which is in a range of a few degrees. They are very focused from close but become huge beam at a distance. Even with lower then one degree divergance in few hunred km distance the laser beam would be still around a kilometer wide.
@@Neo-vz8nh I have a feeling that if their testing concluded the atmosphere is the factor causing it to lose its effective range, I would trust their word and assume it would work fine in space. These are engineers we're talking about - they probably had the laser's divergence in mind when calculating the original effective range

@@G0rgarcut him some slack paying bills is honestly more important. And the people who come here often are educated enough to understand that he did the marketing out of desperation and not because he actually endorses it.
Kyle Hill did a (as always) hilarious video analyzing the death star laser, determining that it would destroy the deathstar and everyone in it with hundreds of G of recoil.
He did? Then I assume he made a math error, since the recoil would be the least of their problems :-) Even at 99.99% efficiency, the laser would produce enough waste heat to instantly turn the Death Star into an expanding cloud of plasma at around 20000K. They should vaporize before they could feel any recoil.
You forgot about the reflection part

@@wernerviehhauser94 "Even at 99.99% efficiency, the laser would produce enough waste heat to instantly turn the Death Star into an expanding cloud of plasma at around 20000K"
They use the same tech that they use to energize the ridiculously dense power packs used in blasters and thermal detonators to store the waste heat until it can be dissipated safely over time via a stream of high-energy ions. As long as the exhaust port remains clear during the years-long dissipation process, they should be fine.
(hat tip to Irregular Webcomic ofc)
Hopefully you had the right cartridge for your mask. But even wearing a mask, chlorine gas absorbs through the skin too and that mask wasn't a full cowl or even a full face mask, so it can be exceptionally dangerous. Best to do it outside if at all.
I was going to suggest a fume hood.
That cartridge looks like the right kind, a multi gas (including organic vapors) cartridge.

Great video. One nerdy thing: The Death Star did use pulses. My brother and I had a longstanding argument about this because we're very mature people. The remaster shows it as clear as day - There's a targeting laser but pulses are what destroys Alderaan.
You can handwave that pulsed lasers are more effective because they give the material burned off the surface time to drift away. Otherwise the clouds of material can obscure the remaining undamaged surface.
High power continuous lasers suffer from a problem called 'blooming', where the energy in the laser beam ionizes the air and causes a spreading lensing effect that defocuses the energy of the laser at distance. It's part of the reason why most modern laser weapons are pulsed power and not continuous. They get their shots off so fast that the air doesn't have time to ionize before the energy has been put into the target.
@@jamesphillips2285 Probably also helps when each pulse targets a different part of the planet, causing an explosive chain reaction in the crust
The Death Star primary weapon is not a laser though it does use lasers for aiming. It is a directed energy weapon that uses a form of beam energy that suppresses the nuclear Strong Force, causing atoms to fly apart with the same energy release as thermonuclear fusion reactions. ALL the matter the beam contacts reacts in this manner., which explains the destructive consequences of even a light strike.

Would have liked to hear about singlet oxygen's disinfectant properties. Our own immune system makes small amounts of singlet oxygen as well as other reactive oxygen compounds/radicals (and even hypochlorite) to attempt to kill invaders.
And our leukocytes light-up as they use oxygen in this manner.👍
@@kennethmiyasaki Indeed -- I found 2 articles on this with a cursory Google search, although they both say that the wavelength of the light thus emitted is 1270 nm, which is in the infrared -- detectable with the right instruments, but not by our eyes.

6:42 that shout out is so deserved when talking about lasers! He is amazing!
Little note from a nerd: Star Wars blasters aren’t laser guns, they shoot plasma bolts.
Cool video as always
OK now I'm curious. Is a plasma bolt just the electrons off of an atom 'bottled up and shot in a stream" whereas laser is a stream of protons, or electromagnetic radiation? Yours is the comment making me think at 3 am lol
Lasers emit a stream of photons, not protons (although, other particles may also be present). Plasma is an ionized substance that has been charged (electrified). The ions in the air become charged during a lightning strike and generate very bright plasma, for example.
thank you @@benb8075 that helps. so, a photon is a particle or 'chunk' of light i.e. electromagnetic energy with no charge, where as a proton is a positively charged subatomic particle. So blasters shot photon bolts?
I was involved in some of the potential basing studies for the YAL-1 if it were ever to be deployed. No joke, the considerations on the ground for the chemical farm were pretty serious. And the aircraft itself was a flying toxic chemical storage facility. It would work, but mitigating the risk from the chemicals involved was problematic.
I'm actually surprised styropyro hasn't made one of these lasers yet, considering it combines his love of both chemistry and lasers

It's funny how the laser project worked but was decommissioned because of "dangerous chemicals".
As opposed to B-2's and B-52's carrying fissile heavy metals to make everyone feel safer.
Fissile heavy metals don’t explode when exposed to air melting everything around them.
Even angry glowing rocks need to be sufficiently provoked before you get a big boom. Otherwise it’s just a little poof and you launch a manhole cover into space.
I’ve been telling Styro for ages now that he needs to up his chemical laser game, glad you’re on board!
Ya'll ought naught temp that young man. 😅
Where I work we had a Trumpf laser cutter that had a 1.8kw CW square folded gas laser. When it started to show its age, we bought a Salvagnini cutter that had a fibre laser of 4Kw power. We were told not to use both at the same time but the suits ignited the warnings.
All of a sudden, the lights literally went bang, and we’d blown three 250A fuses and the t” cabling in the street, which had to be replaced. Office staff swarmed out of their cubicles in panic, coffee going cold, and I was summoned to turn the whole building off and change the fuses.
The inefficiency and power that lasers use is no joke!
Very cool experiment! I had no idea about singlet oxygen, and the photon it gives off as a result of that reaction.
Science is impressive and extremly fascinating and salute to guys like u who actually explain each concept while doing it in practicle .
I love ur way of explaining and just everthing...❤❤
@@HeisenbergIsHerenuh uh
This is the most amazing chemical reaction you’ve ever shown on this channel. Holy s***!!!!! It’s scary to think what a one megawatt laser could do when just a couple watt laser with a small focus lights things on fire from across the room 😅
Also small correction: ultra high power electric laser diodes I believe are usually pulsed to maximize the average power output with the diode’s duty cycle capability in mind. Delivering thousands of watts continuously isn’t an issue. By pulsing the incoming signal, the diode can emit a higher average power level than if it was running continuous duty, and the peaks will be hotter upon contact with the material the laser is cutting optimizing the performance even more. There are actually laser diodes that pump out thousands of watts continuous duty now (mostly infrared ones in the 1100nm range). Backyard scientist had a 2kW cleaning laser on his channel and that thing is literally a deadly weapon 😅
Now that is the best chemistry experiment I have seen in this whole month...❤
That was actually really interesting! Glad I subscribed!

Are we seeing the dynamic range of the camera color sensor failing to acquire the red, or is it that the intensity at that monochromatic range is simply too great for the sensor? Given the lack of automatic exposure compensation, I'm going with the former case. However, it's possible the camera was set at static exposure. Interesting technical for a camera operator and camera designer. I'm curious to hear your thoughts.

Blasters are so uncivilized..
@2:35 Yes, I remember Tarkin pausing to thank Ferreo on behalf of the Galactic Empire after obliterating Alderaan.
My dad played a tiny part in the YAL project. Was pretty cool learning about it.
What would be the power of the reactions you showed us, and how the light is converted into a beam ?
A laser works by exciting a medium like a gas or a crystal with "normal" light or high voltage,or heat. Then to the left and to the right of this medium there will be a mirrow. One of them is semitransparent.
So i think this light coming from the reaction is used to excite the medium. Then when this medium is excited some atoms in it will de-excite by coincidence and release a photon. This photon then bounces back and forth between the mirrow, and by this hits other atoms in the medium, which then get de-exited by this photon, and thus release another photon with same frequency and same polarisation and same phase. So then two photons bounce back and forth, then four, then eight, ... . Then due to the fact that one mirrow is semitransparent, with some probability a photon will pass. These passing photons then make up the laser beam, which is very directional, coherent (same phase) and polarized and with high intensity.
@@neutronenstern. The light created by the chemical reaction is the laser. It's not used to excite anything. It gets collected by mirrors and passed through lenses to direct it onto the target.
@@kmoecub Great, now I wonder why it emits 2 diff wavelenght 762nm and 634nm and if this count as "monochromatic" when technically it emits in 2 different frequency ?
@@CraftyF0X Monochrome also means that it (could be) is a value of one colour as well, so depending on the definition you use, it could mean that as well :)
@@kmoecub LASER means Light Amplification by Stimulated Emission of Radiation. I think you should stop and reread the encyclopedia section about lasers.
If you don't leverage excited states then emission is probably not gonna deserve to be called stimulated but just spontaneous. The benefit of excited medium and stimulated emission is that the light is coherent, the exciting beam and the emitted beam go parallel at the get-go.
The method with mirrors and lenses does not allow creating a straight beam of the laser kind, from a spontaneously emitted light (that travels in all the random directions). Try it. There was an Action Lab video about it too.
You might like reading up the lore for laser weapons in the battletech/MechWarrior universe. Chemical lasers were used prior to better power supplies (IE Fusion reactors)

Sounds like an excellent target to get a hypersonic missile strike on. Wouldn't even need much in the way of explosives to cause a shitload of damage for free, you'd just need to breach the containment structure conveniently located right next to the weapon you want to disable.

1:20 The death star laser is also pulsed, but charge over minutes and fire over seconds, not pulsing on the order of milliseconds.
It's not pulsed. That would be like saying that naval artillary is a fully automatic weapon, but it takes minutes to chamber the projectile instead of miliseconds.
@@kmoecub How long a laser fire is no longer pulsed in your opinion? Is there a rule? 😃
The only way the 'laser' on the Death Star could have had such destructive force (in-universe, or otherwise), would be if it was 'pulsed' in quantum wavelengths; functioning as a 'disruptor' more than a 'laser', basically.
Disruptors exist in-universe, and even 'laser guns' in Star Wars are not a laser beam weapon, they're a laser-excited 'packetized' energy-projectile DEW.

Chemical lasers are equally as interesting since they tend to be chemically venomous by themselves separately, yet when you combine the substances together, they react violently, to the point they give up a lot of light that can then be selectively amplified. It's just attractive to the military because it means they don't have to drag the nuclear power plant across the road (considering the fact that diesel fuel is a precious commodity nowadays, especially with the price - it all adds up quickly).
Yet for shorter laser wavelength, electric lasers are best for that because of energy required to obtain UV and X-ray laser, while chemical lasers are much more efficient in the Infrared and red bands.
Chemically venomous?
@@MirlitronOne It's more of a figure of speech, some chemicals involved in generation of laser light are just as dangerous - like the Halogens in general, in this case Chlorine.

Pulse lasers also allow the vaporized material to be pushed out of the way in between the pulses, increasing the efficiency in cutting power.
The strongest laser light must be seen even from a thousand miles away. I'm almost certain it can cut through anything it passes.
yes

Probably

The laser that was first used to measure the distance to the moon and how that varies, travel 240,000 miles (on average) was only 14,000 Watts. It didn't cut through anything because of the short duration of the pulse.
I really appreciate that he knows about Styropyro
That shoutout at the end is the kind Im here for haha.
Science channel advertising BS snake oil, wow
The science behind it is well documented.
What

This is a great video, but I'm a little disappointed in your sponsor this week. You're an ambassador for critical thinking and the scientific process, making content that is well researched and founded. Snake-oil beauty products that have no medical or scientific backing feels a little....not right. I'm glad you're getting sponsors, I think you totally deserve it, you make awesome content, but I hate to see you hawking something over-priced beauty crap that "gives you chiseled skin."
I'm not advoating for snake-oil, but did you read any of the studies he cited? Did you take a moment to consider that the product may actually do what it claims to do, at least to some degree? I'm not critical of your stance (in fact I agree with it), but to comment without checking things out is as bad as selling snake oil IMO.
@@kmoecub I have seen way too many beauty products in my lifetime to take any of this nonsense seriously. If somebody that actually figured out something that made you look younger, it would be literally everywhere. We're talking electrode belts and laser masks here... They all have "scientific studies" that support them, and yet they always die off in oblivion because they don't actually work. Cherry-picking information, mayfacuters running their own strides, manipulating statistics to sell products is all standard fare and is not the same as legitimate scientific or medical backing.
@@kmoecubI did, one was from China and the other was from the Nu Skin R & D department, a known sketchy MLM company.
It's not the first time he promoted this BS and looks like it won't be the last.
About the spaceship at the beginning: I saw that movie about 5 years ago and I still remember that scene
Good demonstration and presentation. 👍😀

Never thought of seeing a beauty add on this channel hahaha
That dual wavelength color is so neat. It's almost like a magenta-red.
