PRINCIPLES AND WORKING OF A LASER _PART 1

[@PhysicsBanglaTutorial]

Very helpful video to understand Laser working. Thanks sir💟. Watching from 🇧🇩

[@lovely_ji]

you have pasted your flag instead of country name as if everyone knows your country or if it's a superpower🤣

[@PhysicsBanglaTutorial]

@@lovely_ji I think you understood. So it is enough 😊

[@미스타윤]

Smaller videos like these are much better and simpler than Mit or Cornell open course lectures ...

[@devotee6863]

Awesome, superb, fantastic, I don't find words to express my happyness; thank u sooooo much

[@PavanKumar-kf7cm]

Good explanation

[@مروه-ث5ر]

please where is the video for " Stimulated emission " ?

[@TheIancross]

Please narrate my life. Thanks.

[@sukanyasukanya4615]

it's help up all students thank-you so much

[@57nandinirandhe7]

Nice

[@Malayjpatel]

I have a question in my mind: So when the electron(let's say in orbit K) has absorbed a photon and has moved to a higher orbital (Orbit L). Stimulated emission, as I understand brings the electron down again when additional photon is incident on it, so why doesn't the electron in orbit L absorbs one more photon and move to an even higher orbital (say orbital M)? Is the energy level of Orbital M too high for the electron [i.e more than 2 X hv (energy of one photon)]?

[@zainabkhalidh1475]

Is induced emission and stimulated emission same thing?

[@strangewarrior8131]

Yes

[@nandinisilveru9144]

Thank you sir...great explaination...

[@s.bhaveshvarmaec-0386]

What is mean by coherent and incoherent

[@1anu_ra-dha.]

Thankyou sir 🙏

[@utopiasound9328]

l'electron lorsqu il se dép^lace du niveau bas au niveau haut crée un vide potentiel orienté et le vide potentiel orienté perturbé du champs de la gravité absorbe les pzodeon positif et crée l élément primaire du photon : n(1) nombre ricta q(2) quantité de pzodeon crée par le rassemblement de nombre ricta de pzodeon équivalent au déplacement d éléctron dopé positivement. l équation de shrondinger généralisé est la suite : n(1) x q(2) = fonction zeta (1/n(1) * Ex - Eg)

[@issup05]

where is the video for the "characteristic properties of Lasers"?

[@7activestudio]

Hi Issup05 as you requested for characteristic properties of Lasers we have uploaded today please check it. kzbin.info/www/bejne/eHy5fqpqn9V3kNk

i dont mean to be offtopic but does any of you know a tool to get back into an instagram account? I somehow forgot the account password. I appreciate any help you can give me!

@Sincere Ivan instablaster :)

[@sincereivan8538]

@Jasiah Marvin thanks for your reply. I got to the site thru google and Im in the hacking process atm. I see it takes a while so I will get back to you later when my account password hopefully is recovered.

[@sincereivan8538]

@Jasiah Marvin it did the trick and I now got access to my account again. Im so happy:D Thanks so much, you saved my ass !
