Working Mechanism of Ruby laser

[@evanrutherfordlazyahole9079]

This totally helped me understand population inversion better.

[@AmaanYousuf]

This was really helpful...thanks a lot

[@madinasushma8521]

good

[@physics4students419]

You're welcome!

[@radhabears8206]

Very good explanation tq ma'am

[@tuckjagadeesh7094]

Thanks for animation explanation

[@srsrt6979]

Very good explanation

[@ajinkyaingale1490]

Very useful video for me.... Because of this video I secured out offmarks in physics. Thank u so much plz make such more videos so that students can get benefitted

[@prayanshsharma1832]

Tnks

[@AshokKumar-vy3gj]

There is no radiative transition from E3 to E2 level. Why??

[@akshatpandey9141]

As the electrons present in e3 to e2 level do not lose energy

[@loyanganba9722]

very well explained

[@muzalia5938]

Why radiation correspond to E1 to E2 state energy difference is not given to ground state electron to promote it directly into E2 state rather then in E3 state?

[@senapathi6394]

Excellent

[@aazamchamadiya8299]

E2 to E1 , electrons which come by stimulated emission or spontaneous emission ??

[@shibu5598]

"conventional" lasers (such as the ruby laser) rely on stimulated electronic transitions to amplify light. Raman lasers are optically pumped

[@shibu5598]

A ruby laser is a solid-state laser that uses a synthetic ruby crystal as its gain medium.

Superb

[@joy-jc1cl]

osm 👌👌👌👍👍👍👍

[@agritechlive9992]

Energy level 1 and energy level 3 and LED lamp how many find it to electrons but how

[@NinoNiemanThe1st]

That will be $1.69

[@aazamchamadiya8299]

Anyone please reply

[@gopikavarshinilagudu6103]

Very good explanation
