How a LASER DIODE Works ⚡What is a LASER DIODE

In this chapter we will see how laser diodes work, an essential component of electronics with uses in multiple areas.

That is a very useful explanation, particularly the photon entering the hole at the same time as the electron occupied it in an excited state.

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

[maleeshapriyanjana]

Great explanation. The properties of laser are hard to understand. This video made it easy

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.

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?

[OMNI_INFINITY]

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

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.

I am proud that i can already nail the laser acronym

🙏🏼🇧🇷👍
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.🍀

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

[Pravinsahu-qfbb]

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?

[dclopez]

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

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