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
@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 TH-cam also..
But atom doesn't directly excite in metastabel state... Plz explain it. In 4th level laser system atom firstly in higer energy level then goes to metastabel state... But how u can say atom excite in 3s and 2s metastabel state...?
@@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.
Sir you are saying quartz absorbs minor wavelengths , then it should absorb 6328A which is the minimum since it is 0.6um less than the other two but you said the opposite, plzz explain
He atom no is 2 and neon atomic no is 10 so electron move in one circle according to Pauli law elecctron live in pair so he energy level will 1s &neon atomic no is 10 so there are 10 electron live in 2&8means 2s energy level 2electron &2s2 and 6 electron live 2p level He_1s2 Neon_1s2 and 2s2 and 2p6=10 electron

I knew the reasons for it.
@@pavannnaini Can you please explain what are those 2-3 S and 2-1 S energy levels of He ??
Thanks sir, helped me very much for my tomorrow test..... Tq sm
thanks
Your teaching is too good sir. Simple language and excellent explanation. Thanks.
Clear explanation sir. u helped me for my tmrw exam.thankyou so much sir
Thank you so much sir...... Very perfect explanation sir🙏👌👌
I have seen many videos but no video has helped me this much.well explained.👌👌
very clear explanation n extraordinary sir ..
plz upload video about... semiconductor diode Laser (Ga-As laser )
Sister did sir upload semiconductor diode laser
Thank you sir I have an exam on this question tomorrow and like your teaching very much sir
keep going raa this Bharath from Nec this very useful full to supply and who r absent for the class credit goes to our sir and reddy
thanks
Seggamsudha rani I
Best explanation and literally more clear and easy to grasp😊
The way u teach is great... Sir....😊
Best explanation👍👍👍
Nothing can be better thn this
Sir an amazing video...All the things got cleared without repeating the video..Ty sir for such an osum videoo
I am supposed to give a seminar on this topic this helped me a lot
Sir super explanation with clear matter explanation thank you👌👌👌👌
Very nice explanation sir.
Very clear explanation sir thank you
Best explation ever seen on this topic
Thanks sir
Excellent explanation sir,I understood it much ,it was very interesting to hear in your explanation sir,thanks for this video sir
Sir, can u explain how the lasers emitted from 3s-3p, 3s-2p and 2s-2p energy levels.and how can we calculate those?
Nice explanation sir , thank you sir
Sir, you teach this topic very well. 👍👏🙏
Sir could you explain Michelson interferometer and Lloyd's single mirror and wedge shaped film questions
Yeah... Thank you so much.... For this.... Very good explanation sir... Tqsm....😊😊😊😍🙏🏻💐

In 4th level laser system atom firstly in higer energy level then goes to metastabel state...
But how u can say atom excite in 3s and 2s metastabel state...?
sir excellent teaching style
wow what an explaination ............excellent sir ji...
sir but why 2p is having lesser energy than 2s? and 3p than 3s? the order goes as 1s
Could u explain it?
Excellent way of teaching.
Thank you so much
Good explanation John.
Dr.M.Srinivas
thanks a lot sir
Chala baga cheparu Sir
Sir my doubt is that in most the books the ratio for he ne is given as 1:5 ; 1:7 ;1:4 which is correct sir pls reply
10:1 is correct
10:1
Hi
Super sir very gud explanation 👏👏👏
very clear explanation thank you sir
Tq sir helped me for tommorow exam
Same engineering bro
Always my respect to south indian scholar..................
Sir how two different gaseous could have different pressure at same time
super explaination sir. meeru thopu .
Well explanation sir..👍👍
Good way of teaching sir
Why 1s is not in ground State in ne lvl diagram ... Please explain
Tq....... sir ur video helped me a lot in my preparation time....
Super explanation sir thank you sir
Informative sir
Sir thankyouu soo much this made my answer so simple to understand!! Very good explanation indeed!
Very well explained sir it helped me alot again a big thanks sir
there are many ads....it is really disturbing..... -_-
Ads are controlled by Google, not the uploader.

@@HighbrowDirector ohk... Wasn't aware.. my bad
@@akhilblackcobra It is not necessary for anyone to know everything. You may have a better knowledge of something else. Don't hesistate to share. ;)
Very True...There are too many ads....(I have come across 5th ad. and seen only 7 minutes video.).
Sir, you are a great teacher
Could you clarify me about 2^3s, 2^1s, 3s, 2s.i didn't able to understand those??
Thank you so much sir 💫 very useful information
What is the use of the mirrors placed beside quartz chamber
Sir why we can’t get any photon when atoms transition from 2p to 1s … if photon emit then what’s happen?
sir please upload the working Nd-YAG Laser and its construction . You are very well explained all the concepts very clear. sir.
thank you
Thank u sir u help me a lot . very nice video
Well done sir.. Hats off to you........
Excellent sir...
Thank u sir it's very helpful
very well explained sir...
Thank u soo much sir it help me a lot
Super teaching sir
Very good explanation....sir
Tq sir really I got clear explanation

Thank you sir, very nice explanation
Amazing explanation👍👍👍
thanks
U explained in very depth thanks sir..
thnks Sir it such a simple and easy to understand
god level explaination ♥️
Sir can u explain semi conductor laser i have my semester exams sit it would be helpful
Yeah...I also need it for this sem
Super explanation sir ,tq very much
Sir I need fermi _dirac distribution
Thanku sir
😊😊😊😏
Nice concept
Very nice work sir!
Nice explanation sir👍
Thank u sir i have subscribed your channel
Very nice. Explanation 🙎
best explanation of such an interesting topic thanks sir it helped me lot i subscribed
it is very helpful in understanding he ne laser thanks sir
PV=nRT so shouldn't it be the same thing, if the pressure is 10:1 units the number of moles would also be 10:1
Thanks alot sir ...it helped me alot n i can understand the topic clearly once again thank you so much sir...n I subscribed it..
Awsmm lectures sir thnk u so much
Thank you sir for such a great explanation
sir semiconductor laser ki bi video u-tube per upload kardo
Tq u sir and l lvd ur explanation
Thank u very much sir.....🤝🤝🤝
Aswome sir u helped me alot
Sir, what is that 2-3 s state?
He atom no is 2 and neon atomic no is 10 so electron move in one circle according to Pauli law elecctron live in pair so he energy level will 1s &neon atomic no is 10 so there are 10 electron live in 2&8means 2s energy level 2electron &2s2 and 6 electron live 2p level
He_1s2
Neon_1s2 and 2s2 and 2p6=10 electron
Sir u where awesome thanks for this vedio.....
sir make a video about tem.we cant find it anywhere.
Nice explanation sir tq
Sir, can you make a video on semiconductor laser..
You explain the concept very well but so many ads in between is very annoying
thanks
Very much thanku sir🙏
Can u explain schrodinger equation
Superb
Why we use He and Ne in 10:1 of Hg pressure
Sir, can you explain semiconductor laser
Excellent sir
very well Explained...!!!
