population inversion of laser

[@sreevidyaps3728]

Good job. I couldn't find a class in English . And u did it 😄

[@visheshsura6624]

Exactly😄😄

[@rakeshreddy2329]

Search English in search bar could help didi

[@SouravSaha-el6pk]

But I need Urdu 😂

[@sidharthakumarsahoo2801]

Sir your teaching level is so high that anyone who sees your video can't lose anywhere related to that concept

[@Probot13g]

Thank you so much! You covered it more clearly and quickly than textbooks did.

[@srigowtham5215]

Simply Awesome sir 👌👍👌

[@abhishekfrfr]

never seen such effective teaching since a very long time thank you very much sir

[@punurulikhithareddy3912]

Nice sir baaga cheparu sir meru

[@iqrakhan560]

Why population inversion is necessary in a laser system? Please answer

[@sanamrakesh3157]

Great job sir thank you very much

[@jillurrahman6812]

Thank u so much vai .I have very doubt in this topic.you covered it more clearly ❤️❤️

[@archithvenkatesan2844]

Thank you 🥰

[@manasayanaki1299]

Thankyou so much sir
...I think u dont believe that I have exam today and I watched it vedio about population inversion and I get this qxn in my exam..it's unbelievable.. I wrote that what I listen from Ur vedio...thankyou so much

Thank You for ur great classes sir

[@michaelgloria1682]

Will the electrons in the metastable state move to a higher energy state if supplied with energy?

[@yashii5903]

Is it possible to supply energy to the metastable state??

[@riddlemaster252]

Really effective..... Your one class is way more better than myr whole semester study 😂😘😘😘😘

[@yashpunk3215]

You are great , thank you.!!

[@muhammedrishadc4296]

You are excellent ❤️❤️❤️

[@MaheshKumar-nh1gt]

Superb brother!! Many people don't have that fluency as u have!!! Keep it up!!

[@mohdidris4985]

No IIT sir can also explain this
Hatts off

[@TejaswaniARTS7340]

Sir why we are calling E2 is metastable state and what is the meaning metastable state

[@chagantipatiharish8485]

Super... Sir..ur vedios Clarty and clearly...

[@memorialpapang952]

Thankyou so much Sir, God bless you!!

[@chanvika_6994]

But how can an electron return to it's ground State from a metastable state sir?electron transmission is banned in the metastable state na?

[@eshakhan2830]

because of the stimulated emission process i think so, not sure

[@rajashekhargangadhari778]

I'm learning from your videos to teach my students it's very useful to me sir thanking you sir

[@AbdulKader-mk8kw]

best explanation

[@AdityaSingh-td4px]

Sir please make a video on method of section including moment👍 Great tutor

[@visheshgiyanani7006]

Thank u so much

[@MrAashuverma]

Sir, plz continue some topics of semi conductor

[@scienceathome4426]

In all the lectures of population inversion they say atoms instead of electrons...what is the correct one can anybody tell me please?

[@runuroychowdhury6825]

elections

[@bharath4884]

electrons

[@samathaallu8175]

Electrons

[@rinisha5679]

I am so lazy to study physics and maths but now my exam is coming and i searched and finally came here it's very understanding and nice cls now there is a little hope that I can study🔥😻

[@prabinshekhar7054]

Please Recommend books

[@saromnous-md5590]

good video, thank you

[@saineeraj1326]

Sir make a video about semiconductor diode laser..your explanation is excellent

[@Manzarnamaa]

Thanks was looking for this one👍👍👍👏👍👏👍👏👍👏👏👍👏👏👏👏👏👏👏👏👏👏😘

[@David-hw7uj]

Are Metastable state and excited state same?

[@AniketPatil-gm7kw]

Life span of atom in excited state is 10^-8 seconds and in metastable state is 10^-3 that's more than excited state.

[@qasimmushtaq1545]

AMAZING SIR
LOVE FROM PAKISTAN

[@sidharthakumarsahoo2801]

Sir plz upload more videos that will benefit all students

[@kavitaarya5567]

thanku sir

[@itsjyoti1883]

Gud video☺☺ clear this concept so easily

[@tracedis7843]

very nicely explained thankyou:)

[@Sana_rover]

You are saying atoms, actually, it's the electrons. Also, according to Pauli's Exclusion principle, two or more electrons cannot occupy the same quantum state. Then how can u achieve population inversion in the same metastable state?
Can You please explain it.

[@afshankhalid809]

During transmission from E3 to E2 why there is no emission of photon?

[@cottoncandy4423]

Answer pta chale toh mujhe bhi bta dein. Please. I'll be very thankful 😊

[@sidharthakumarsahoo2801]

Physics related videos upload kijiye sir

[@grenade1878]

Yeah channel phele kyu nahi mila mujhe

[@tharunreddy8471]

Sir please give a lecture on co2 laser !!!!

[@vishalgowtham896]

Very helpful , thank you sir

[@sanathshetty9130]

Thanks alot sir..it indeed helped me alot

[@nazishara1735]

Excellent

[@mzzaka_009]

How we will achieve Metastable state in atom ?

[@SARDAPRANEETH]

Sir super explanation sir

[@enthusiastic45]

Nice video 👍👌 sir sir stimulated emissions ka video banayiye

[@aadilbhati6708]

Thankyou sir please write on some thoury topic

[@manoharlekkala2753]

Population inversion is done in excited state or meta stable state

[@kumarpurushottam632]

Thanks a lot sir

[@narasareddykaliki7987]

Well explained

[@bhamuzasiphamandla5560]

thank u
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@harmanpreetkaur3902]

excellent experience .sir plc explain broadening of spectral line topic of bsc.2nd year

[@eTution]

thanks

[@simransimi7034]

sir please make a video on topic broadening

[@harshchoudhary3258]

i will just say wow ....

[@kandupidradei]

why the hell u referred electrons as atoms and every shit people in cmt section agree with you

[@UvvM_Records]

Nice

[@karthiksende2692]

Sir we want domain theory of ferromagnetism

[@sidharthakumarsahoo2801]

Demand bahat achha hai

[@ijazkhanniazi800]

Sir metastable state ki proper definitionto baye plz

[@mahsaabidbid5775]

Amazing

[@surbhikakumari7581]

I would like to correct you that its not the atoms that move on supplying energy, it's the electrons which move. Atoms are immobile.

[@musicfastnavy3988]

thank u so much sir

[@itshari5489]

Thanks sir ...

[@santoshkumar-wd2fq]

Sir i feel jealous ur not a faculty in my college😫😭😭

[@sakshimahajan3969]

plz add the exercise of physics fybsc

[@nidhi4545]

Thank u sir

[@eTution]

please subscribe and like our videos and follow our upcoming videos

[@reetwik8870]

Thanks sir

[@siddhartharaja9413]

Thank you sir

[@okabae7927]

this doesn't explain metastable state clearly. Very very basic.

[@BG-qf7kc]

Electrons or atoms

[@SARDAPRANEETH]

Sir please explain Ek diagram

[@outstandingiron7775]

Its electrons, not atoms.
