HELUM -NEON LASER CONSTRUCTION AND WORKING ( HE-NE)

[@pavannnaini]

I am teacher with two years experience. This video is fantastic. Most interesting parts in this videos are about quartz, resonance transfer, Brewster angle . These concepts made it more clear. Ur a great teacher sir. Ur inspiring teachers also

[@UnExplorateur]

@insert username People don't ask about logics, just follow the description.. Nobody asks why the He excited level is equal to the Ne excitation level.. and why there are two different excitaions.. so many questions to follow.. and these topics about different types of lasers and their working are not well explored in KZbin also..

[@pavannnaini]

I knew the reasons for it.

[@UnExplorateur]

@@pavannnaini Can you please explain what are those 2-3 S and 2-1 S energy levels of He ??

Very much thanku sir🙏

[@PriyankaYadav-kn4hi]

Sir u r tooo good...

[@botarun8781]

sir but why 2p is having lesser energy than 2s? and 3p than 3s? the order goes as 1s

[@aabidmushtaq3243]

Could u explain it?

[@netkrish8371]

Sir why we can’t get any photon when atoms transition from 2p to 1s … if photon emit then what’s happen?

[@botsakiransai1558]

Sir I need fermi _dirac distribution

[@saisureshsanapala6292]

Could you clarify me about 2^3s, 2^1s, 3s, 2s.i didn't able to understand those??
