Threshold Condition

[@ШубертМенян-АВТОЗАПУСКВМЛМ]

Thank you for your lecture sir!🙏💎💯

[@SONAMSHARMA-ht9yy]

You gave a nice mathematical approach and it helped me a lot!!

[@jacobvandijk6525]

The units of the Einstein B-coefficient are: m^3 / (J.sec.)

[@nastyavicodin6229]

Thank you, very good explanation!

[@sm-pz8er]

perfect explanation thank you

[@ARCSTREAMS]

would be nice if you used the formula for actual laser design parameters so we can see how each variable is worked out ,for example how are loses measured in ? units of what?

[@aniksingharoy59]

Thank you Sir.✌❣

[@Indiawithignis]

sir, very nicely explained... please arrange videos of noise in detectors

[@DeepSingh-wo1tt]

Excellent!! Sir I am studying CO2 laser , I want to calculate : 1) Cavity dimensions with gas volume and its input power requirement 2) Its output power 3) Gas pressure Hope you help me, I shall be very thankful to you

He made these videos (in 2017!) for his job, not for his own fun. So don't talk to him in person, talk to his employer!

Threshold condition for oscillation sir

[@rashidinfo]

Sir how we calculate synchronize oscillation of ruby and other laser????

[@pankajgautam769]

Nice sir...thanku

[@avneeshcheenu5918]

Sir please explain every term you introduce .... And please don't be nervous, It looks like you are just vomiting what you have mugged up (which u haven't) ... Just be free with us

Teaching is a art and everyone has his own way/nature. By far he has explained the best for basics of Lasers among available lectures. Prof. Shenoy Lectures are also there (Semiconductor Optoelectronics)

[@jacobvandijk6525]

@@himanshuful I would say teaching is a profession you can learn. Didactics give people basic rules how to transfer their knowledge the best they can. Unfortunately, many teaching academics have not seen a book on Didactics in their entire life.
