Thank you. I have watched several videos on the FB interferometer, but this is the first one that clearly explained that and how all the light is transmitted out the mirror opposite the entrance mirror.
two questions: does from where input light enters light reflected end transmitted from left mirror has 2 times intensity? in confocal interferometer light transmitted from right mirror doesn't diverge?
Yes, that is possible! The amount of light you couple into the FP is however proportional to the mode overlap between the incoming beam and the cavity eigenmode. A slightly focussed beam has a larger mode overlap than a collimated beam. :)
If 100% of the signal is transmitted, then 0% is reflected. However when I try to do the calculations I end up with the wrong answer. How would the calculation for reflection look like? Sadly I cannot show my calculations, because if I do the comment gets removed.
Only if I take the reflection from outside to inside the cavity (r) different from the reflection that occurs inside the cavity (r') with r = -r', then it does add up to zero. Is that true and why?
@@DW-iq8lt I would say that it is precisely what 100% transmission means. Simply put, everything that goes in on one end comes back out the other end. And this is also what the professor in the video is showing and several times stating. Why do you think otherwise and how would you then define 100% transmission?
Thks q soo much sir love and respect from India

Same here the explanation here have me the eureka moment of understanding that's like a drug ! I want more!
Thank you! You are very good at explaining things.
awesome, super well explained and introduced thru a practical POV as well! thank you!
The magic of interference :)
excellent but why dont you have more views
This is an awesome explanation in plain English.Thank you so much from the USA
Thank you for this excellent presentation. I'm looking forward to your next one, is there a way I could follow you on youtube?
Cant read the green writing , its so well explained but cant read
and that's the magic of interference
Thanks you professor for this wonderful course

in confocal interferometer light transmitted from right mirror doesn't diverge?
Thank you for this clear and concise explanation.
Great explanation, thanks for making this!
MARTIN!!! Goed filmpje.
What is nanoparticles based on Etalon?
That's such a beautiful concept!
So helpful, thank you!
Very informative
Excellent Explanation
Question: why do you have to slightly focus inside the confocal FP cavity? Is it possible to input just a narrow collimated beam?
Thanks!
Yes, that is possible! The amount of light you couple into the FP is however proportional to the mode overlap between the incoming beam and the cavity eigenmode. A slightly focussed beam has a larger mode overlap than a collimated beam. :)
Thank you so much!

My mistake. You were right about the transmitted percentage. And at resonance, reflected intensity is zero.
Спасибо!
Thanks a lot
helped a lot on my assignments thank you :)
Good one
Thanks
Fyi I'm just a beginner so it's a little high for me
😐😐😐
Sir bsc2 mai physics ke important question explain kr dijiye
