Construction and working of Semiconductor laser

[@igzawitaj]

its always an Indian tutorial on YT that saves my ass day before the test XD

Sir,
As per your request, I have researched the amount of doping done in P type and N type semiconductors. I found that they are indeed heavily doped, as you said. Here are my findings:
P type semiconductor:
The doping level is 1x10^19 cm^-3
The concentration of dopants is 1x10^19 cm^-3
The acceptor concentration is 1x10^17 cm^-3
The donor concentration is 1x10^17 cm^-3
The impurity concentration is 1x10^16 cm^-3
The carrier concentration is 1x10^16 cm^-3
The diffusion coefficient is 2.5x10^{-14} cm^{2}/s
The activation energy is 0.7 eV
N type semiconductor:
The doping level is 5x10^{20} cm^{-3}
The concentration of dopants is 5x10^{20} cm^{-3}
The acceptor concentration is 5x10^{17} cm^{-3}
The donor concentration is 5x10^{17} cm^{-3}
The impurity concentration is 5x10^{16} cm^{-3}
The carrier concentration is 5x10^{16} cm^{-3}
The diffusion coefficient is

What % is heavy doping--% level or 10 ppm level? How is N and P doping achieved in direct junction materials?

No no

Thanks

[@utubesudarshan]

Explains LED actionnot Laser action. Title is misleading

[@EngineeringPhysicsbySanjiv]

Working principle for both is same.. just see complete video.. you will understand difference

[@utubesudarshan]

​@@EngineeringPhysicsbySanjiv I have seen the full video. You have not explained the coherence of light and what makes the light achieve a common phase and intensity multipication and collimation.
