The best video to explain RUBY Laser, it's construction and working in easy language which helps us to remember for a longer period of time. Thank you Eduphile channel.
I was really very confused in this topic and textbook langauge is also hard to understand.... I was finding this kind of video thank u sooo much sirr for explaining 🙏👍
Sir ap pdate bohat acha h bs notes provide nhi krte or screen shot lene tk ka time bi nhi dete plz plz sir eske bare me thoda sochna es se bohat help ho jayegi hmri
wow... sir.... I am very very lot's of thanks for u.... because your concept is very clear... and knowledgeable..... and your teaching process is outstanding...... again thank you so much sir..... 💖💖💖
So, if there is no role of Al2O3 here, why we are not using only Cr2O3 instead of Ruby????,,,,,,,,,,,,, Cr2O3 is also a solid material,,,,,,,,, please tell me Sir 🙏
To get a ruby crystal to “lase”, you have to raise a majority of the chromium atoms to a higher energy level, typically with a flash of light from a xenon flash tube. Quickly after the flash, those excited atoms relax back to their ground state, emitting a photon of red light. If most of the other chromium atoms are still excited, they can’t absorb that red photon, so the photon gets to escape from the crystal as part of the laser beam. But if too many chromium atoms are still in their ground state, there’s a good chance one of them will absorb the red photon. If you tried to use a crystal of pure chromium oxide, there would be WAY too many chromium atoms to be able to raise most of them to the higher energy state. There would still be far too many chromium atoms in their ground state, and these would absorb any red photons that were produced. The crystal couldn’t “lase” properly.
Kya laser m jo metastable state hoti h vo sare atoms m present hoti h ya kisi kisi m hi hoti h ?? & Kya ise construct kiya jta h ya pehle se present hoti h

How can he save lives ?!!! Say something sensible!
@@sonyehyun3328If he didn't studied then he would have suicide because of KT. So due to this video his life saved
@@SahalKoth-qm2cr you took his. Comment. To a whole another level😂😂
Exactly 😢
not a day before exam , it’s some hours 😂
Bhai aap ke liye dil se dua nikal rha hai 😊😊😊, Thanks brother

Your explanation is really very helpful to understand the concept deeply 🤗🌸 , thankyou for providing such informative videos 🙏🏻
I've always been weak in physics and watching your video made me easily understand the topic very well. Thank you so much sir..
You are most welcome
Kha the sir ji aap ,
Aap phle aisa teacher h jo bht jldi samjh aagya topic aik baar mai wo bhi achese aikdm❤
Thanks and Welcome 🤗
Sir I just watched your video and ruby laser was came in my paper.
Thanks ❤️❤️ so much for this video . I easily understood all the theory very well..
Thanks bro kab se samaj rahi thi par koi acche se samjha hi nhi raha
Ab bhot acche se samjh gaya
Most Welcome 🤗
Watched it in 0.75x speed 😅
But very easy & nice explanation
Keep it up 👍👏
Thank you so much 😀
sir such a you are nice teacher and and your video is very intresting and your teaching method
is very best thanks a lot sir
Everything is outstanding but give the proper view of notes for few seconds so we can take screenshot. Thank you Sir.
Bhut help hoti h ❤❤ sir aapke videos se😊😊
Continue sir for students
Thank You so much for making such type of video....This is really helpful for all that students who wants the proper explanation with notes
bohat bohat dhanywad bhai aapki waje sai finals mai ache marks aeygey aapne 4th aur 5h matlab pura optics kar rakha hai cover
Thanks 😊

Sir Ruby laser me continuously cold water supply karna padega
Glass tube ko cold rakhne ke liye
Ruby laser required a cooling system.
Thnkuu broo❤

All the best
All the best
Love to visit this channel. Awesome explanation
I have a question, why it was radiation less when transition took place from E3 to E2
Because there are no corresponding radiation and energy difference is very less. Thanks. Keep Growing

Kya laser m jo metastable state hoti h vo sare atoms m present hoti h ya kisi kisi m hi hoti h ?? & Kya ise construct kiya jta h ya pehle se present hoti h
Metastable state depends totally on energy excitation and deexcitation
@@Eduphile no i read somewhere tht its only present in some atoms & only such atoms r used to construct laser
Atoms ma present h theek lekin kaise usko excite energy dena hoga aap ye soche
@@Eduphile can you teach in English or tamil
Superbbbb 👍👍👍
