what type of pumping used in common lasers?

[@beerendrabhandaree]

Sir, please upload this notes as pdf. This can help a lot.🙏

[@yuvrajrana.1702]

very very good explanation , great sir

[@ujjwallohiya2266]

Concept clear in one video 👍

[@gamechanger5432]

6:35 Inelastic mei toh energy loss hota hai. Elastic collision hoga, jisme no energy loss.

[@sel5381]

Replying too late but when an He atom collides with Ne, it transfers energy and excites Ne atom, when Ne atom de excites, it releases photons so net emergy loss happens, hence inelastic

how the metastable state is creat??? why the atoms in metastable state take 10 power -3 sec??

[@priyanshusingh3245]

to the point trully awesoooooooome

Apan ko apka lecture achha laga...

Phele aap bole spontaneous main lifespan 10^-8 hota h abh ussi ko stimulated main mix ho raha 🙃🙃

[@ankitamanna03]

Metastable state me transition non radiative ku hoti hai?

Who said?

[@jp_gun5930]

Awesome Bruhhhhh!!! :) ❤

[@Lastmomenttuitions]

Thanks ✌️

[@dracula_69]

1:55 I think that would be *saturation** instead of *situation* ? or am i wrong?

At some points you don't make sense at all, get all your facts straight first and then give us the information! Take medicine for your cold!

[@aloktiwari2428]

Sir metastable state kaise create karte hai.

[@AkashKumar-fv7uo]

by adding impurities.

[@vishalagarwal217]

Where is notes I fill Google form

[@sameeanausheen0803]

Ignore the negative shitty comments....u are fab sir♥

[@suryapratapsingh6801]

best

[@Lastmomenttuitions]

Thanks

[@arkabhattacharjee3386]

But why is there existence of metastable state??

[@muskan5015]

Life time of metastable state is more than the excited state

[@tonmoydeka7319]

why dont you guys give notes ?

[@prashantpathak2068]

Sir aapka camera clear nahi hai

[@ig_sh9120]

Sir we need notes
