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
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
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?

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?
That Waa a great video, cab you make a video of laser modulation and a video of pulsed lasers and a third video about low noise lasers if possible. Thanks 👍
Blue Twin Laser Cannon activate!!! Ever since I was a child I've wondered why does the blue twin laser cannon destroy more baddies in Raptor game on DOS than any other weapon, but in those days I only enjoyed the destructive force on display on my screen. Now I know, it's because blue is more intense laser light.

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.
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.

Thank you so much ... Finally i had the chance to see how the phenomenon can happen
Great explanation. The properties of laser are hard to understand. This video made it easy
This channel deserves 10milion subscribers ❤🎉
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.
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
I thought it was impossible to directly get a shorter wavelength radiation out of a longer wavelength radiation. Thanks for telling me that bro😃

Perfect explanation
Great explanation, thanks a lot
It was very helpful thank you❤
wow subbed immediately😂 thanks
Awesome. Finally get it

*Thanks! So the semiconductor doping amount determines the frequency and wavelength or...?*
Great Explanation, thank you!
Great job sir thanks
Laser beams are coherent.
🎉Good job

A+ material.
Thank you.😊
Nice info, thanks :)
Thank you!
Bravo! 👏🏼👏🏼
Request for videos on photodiodes and solar cells
I am proud that i can already nail the laser acronym
Very goood 🤔🤔🤔😏😏😊😊😊😊🤗
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?
Feel electricity fell electrons,put yourself in an atomic accelerator feel all the subatomic particals
Though i advice do it for only a short period of time
I guess Your question is probably of philosophical nature or what are You asking specifically? I'm asking honestly
The hell do you mean feel? They're literally subatomic, you don't even feel dust particles
Touch a running wire

Can anyone tell me what the effects of some pointing this at someone's head?
Just point a laser pointer on your hand and see what happen, never ever point it at your eyes tho
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
Hmm still hard for me to understand I will continue to keep studying
Your video my frabarid
Something that is a "wave" and "particle"... Can you draw that in 3D? Never mind!
I didn't understand 😢
Solar movi ples🙏🙏🙏🙏🙏
👌👌👌🙏🙏🙏🌹🌹🌹
Gente vamos fazer o youtube dominado por JESUS!
Cole isso em todos os vídeos que você vê!
💛ELE VIVE💛
🔥ELE ESTÁ VOLTANDO🔥
fixa???????????????????????
Any evidence for that?

I think negative to positive is stupid
TL;DR
Computer voice ick!
that's because it is the English dubbed version. If you can understand Spanish, just go to his other channel. he narrates it himself.
This is terrible.
