01:13 Laser is a device that produces a highly intense and coherent narrow beam of monochromatic light. 02:26 Laser beam is a focused and intense light with coherent radiations. 03:39 Atoms absorb photons to reach higher energy levels and emit radiation to return to ground state 04:52 Laser beam requires multiple radiations and active materials with at least 3 energy levels. 06:05 Population inversion leads to emission of radiation 07:18 Stimulated emission of radiation produces laser beams. 08:31 The laser beam is produced through the amplification process using a mixture of Helium and Neon in a discharge tube with two reflecting convex mirrors. 09:40 Laser beams have various uses and benefits

[@kavanashreekavana898]

Thank you for uploading this video because whole chapter is only 10 min ❤😊❤🙏🙏for my end semester exam

Mtlb humne photon se momentum badhaya tha vo atoms ground se excited me jane. Mtlb photon ko mass hai? Pr theory me to likha hota h ki photon ko mass nhi h.

[@zakiramin256]

But photons have momentum. Given by p=h/lamda h is plancks constant. This is because they have energy given by E=hv

[@sufiyapathan9020]

Nice masha allah❤

[@sachinsen9221]

6:17 why won't it go to E3 when it has more than enough energy (requires 1J but we have supplied 4J) to go there rather than coming back to ground state i.e E1

[@muhammedabdulquadirowais4871]

because we require exactly 1J, not 4J...

[@kashijee5310]

Superb method.....

[@tushardey877]

Everything is ok, thanks for your help,but don't start the video as you have started 👍

[@Bestt.comedy]

your video is very nice
