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 ??

Thank u sir u help me a lot . very nice video

[@victoria_3232]

there are many ads....it is really disturbing..... -_-

[@akhilblackcobra]

Ads are controlled by Google, not the uploader.

[@HighbrowDirector]

@@akhilblackcobra Uploader can control it, He can choose whenever the ads should be played. Available options are 1)At beginning 2)At End 3)Midroll and in midroll uploader can manually place where ever he wants or youtube will automatically place ads if we choose those options. While in the manual placement of midroll ads is not necessary to be played. The uploader can put an infinite number of ads in the video but youtube will play an only optimal number of ads according to the length of the video. in the case of these videos, the uploader can choose not to play ad in between so the students will not get distracted in between.

[@akhilblackcobra]

@@HighbrowDirector ohk... Wasn't aware.. my bad

[@HighbrowDirector]

@@akhilblackcobra It is not necessary for anyone to know everything. You may have a better knowledge of something else. Don't hesistate to share. ;)

[@nishantbharwani852]

Very True...There are too many ads....(I have come across 5th ad. and seen only 7 minutes video.).
