Great explanation, thanks a lot

[@boufennaramadjdouline609]

Thank you so much ... Finally i had the chance to see how the phenomenon can happen

[@abdelmoneim3796]

Perfect explanation

[@Bianchi77]

Nice info, thanks :)

[@dzdawlatzwamel9795]

Amazing video, thank you

[@asmiyuka3324]

Awesome. Finally get it

[@MikkoRantalainen]

Great explanation! I would love to see more videos about this stuff. What kind of doping is required and is the middle layer actually transparent or just so thin (e.g. 1.5 times the wavelength) that is able to radiate the photons even if it's not transparent?
Also, is it possible to create high power lasers with doped silicon only, even in theory?

[@joshuapitong899]

Thank you.😊

[@zhilihuang6609]

Thank you!

[@MarioDallaRiva]

Bravo! 👏🏼👏🏼

[@umargul5644]

Great job sir thanks

That's how I understood it, it's the lens that creates the actual light spot i.e. relative straight beam. This works because the shape (and maybe material) of the lens is specifically made for the wavelenght.

[@educationaltechnology8363]

wow subbed immediately😂 thanks

[@jensschroder8214]

Green lasers often consist of an infrared laser and a crystal in front of it that glows green.
Therefore, they then emit IR and green light.

[@WolferAlpha]

The only advantage of this is having a very precise wavelength (since this system uses resonance), but if you need it to be very compact, you have, for example, the NUGM06, a green diode laser with a 2w output, but it needs almost 15w of energy

[@frommarkham424]

I thought it was impossible to directly get a shorter wavelength radiation out of a longer wavelength radiation. Thanks for telling me that bro😃

[@GABRIEL-dz9mh]

More expensive ones don't as they have an IR filter. But if you want a compact, more rugged design there are 520nm green lasers that are a diode and lens just like the hugely common red pointers. But 520nm are expensive if you want high powers over about 1W

[@josephinemwangi6612]

🎉Good job

[@OMNI_INFINITY]

*Thanks! So the semiconductor doping amount determines the frequency and wavelength or...?*

[@Aliali-mk6jq]

Good way to explane

[@reinhardkuster4917]

Great Explanation, thank you!

Thank you sir, this clarifies a laser diode a lot. Let me ask for two more questions?
Why light is not escaping from "sides" of the gain media?
Also, why there is directional dispersion? Is it due to short length of the Fabry-Perot resonator?

[@RODOLFO.M.S]

🙏🏼🇧🇷👍
Por favor, me gustaría ver una animación de los electrones moviéndose dentro del circuito ladrón de Joules. muchas gracias.🍀

Please, I would like to see an animation of the electrons moving inside the Joules thief circuit. thank you so much.🍀

[@kayakMike1000]

Laser beams are coherent.

[@peopleicat115]

Very goood 🤔🤔🤔😏😏😊😊😊😊🤗

I am proud that i can already nail the laser acronym

[@susantamaity1486]

Your video my frabarid

[@myyoutube6978]

Can anyone tell me what the effects of some pointing this at someone's head?

[@HPalternetive]

Just point a laser pointer on your hand and see what happen, never ever point it at your eyes tho

[@Term-0]

depends on the wavelength. if it is low wavelength, it would probably just pass through you. if it is low power visible wavelength it would just cast light onto you. if high power, it might feel warm or burn you. if is short wavelength and high enough power, it might give you a higher risk of cancer and/or burn you.

How a LEP FLASHLIGHT modules works

[@Pravinsahu-qf9bb]

How can we identify that it is an atom? How can we feel electron, neutron and proton. What is proton and neutron, can we feel it?

[@ethinesvedi7246]

Feel electricity fell electrons,put yourself in an atomic accelerator feel all the subatomic particals

[@ethinesvedi7246]

Though i advice do it for only a short period of time

[@fickgooglefickthem6884]

I guess Your question is probably of philosophical nature or what are You asking specifically? I'm asking honestly

[@mrfashionguy1]

The hell do you mean feel? They're literally subatomic, you don't even feel dust particles

[@prahlad7191]

Touch a running wire

[@dclopez4889]

Hmm still hard for me to understand I will continue to keep studying

[@koochakjanghali4536]

👌👌👌🙏🙏🙏🌹🌹🌹

[@jatigre1]

Something that is a "wave" and "particle"... Can you draw that in 3D? Never mind!

[@peopleicat115]

Any evidence for that?

Se o fizer, terá vergonha de pessoas desagradáveis como você.você traz vergonha sobre o nome dele. Não seja desagradável, para não ser como os hipócritas de Mateus 6:5.

[@alanday5255]

Computer voice ick!

[@Term-0]

that's because it is the English dubbed version. If you can understand Spanish, just go to his other channel. he narrates it himself.

[@owlredshift]

This is terrible.

[@peopleicat115]

Very goood 🤔🤔🤔😏😏😊😊😊😊🤗
