What is Fabry-Perot FP Laser

[@anantikamehra1694]

Very concise and to the point explanation! Loved it. Thanks for the video.

[@nevermindshort3]

+Anantika Mehra I second that. I study a lasers-course at the moment and the video was helpful for understanding the class.

[@akankshakumar8499]

could not get a better explanation...thanks a ton!! :)

[@kumarsuresh5723]

Very simple and cool way of explanation. Thank you!

[@nandkhidkikar5350]

Nice explanation of F-P Laser.

[@saurabhbedi195]

Very Nice Explanation !! Please upload the tuneable lasers using ring-resonators. Thanks

[@zenlee5826]

i'm an indian &i'm so thankful for your tutorial.i need it but its not sufficient.

[@jpmorgan187]

Please have a seat right over there. - Chris Hansen

[@eXtremeDR]

Great explanation. Just an idea - wouldn't it be even more effective if the mirrors focus the reflected photons?

[@mathk1ng1]

Does anyone know what the receiver of this experiment is measuring? I just did this lab for intermediate physics and found a good wavelength but I'm not sure of the value that the receiver gives me. It's on a scale from 0-1 and has units of "mA". Are those miliamps or an amplitude for the wave?

[@jacobvandijk6525]

For the very, very basics it's not a bad video.

[@NilayJainhi]

thank you for this video...now i actually understood what is fp laser...thank you:)

[@haribaskar1716]

good one... can you please share passive mode locking of laser??

[@jonni2734]

Very useful! Thank you!

[@nikolaradakovic5050]

It seems you have explained mode locking on an example of FP

[@jalalfathisola9899]

Hi there
I needed to learn some about fiber optics and fabri parot.
your videos helped me alot.
Thank you so much.
good luck

[@YasminBello]

could you help me out on how the fp laser connection works

[@memsuniverse]

Thank you great tutorial

[@rakshyathapa7438]

Nice work!

[@elifnurdayi9897]

Great explanations thanks!

[@betabet5714]

Do you have an example of active medium? Thanks

[@kevinsong1056]

very good explanation! thanks!

[@ashishdas7249]

Please produce more videos on optics. There are no new videos.

[@ARCSTREAMS]

cant they make these diodes much bigger?

[@AhmedOsama_119]

Thank you. I wish you added more details. but still, appreciated

[@aswinp.k5779]

Nice explanation

[@ARCSTREAMS]

so wont any cavity length work?

[@jacobvandijk6525]

In theory, yes. As long as L = (1/2 wavelength) x any positive integer, and thus the bigger the integer, the smaller the wavelength.

[@ARCSTREAMS]

@@jacobvandijk6525would 1/2 wave be the minimum and why does it have to be1/2 not less or full ? i never understood why wavelength comes into play

[@jacobvandijk6525]

@@ARCSTREAMS With lasers you're dealing with light and light can be described as a combination of electric and magnetic waves. A wave has a wavelength (in space) and a frequency (in time). The 1/2 wavelength has to do with standing waves in the cavity.

[@ARCSTREAMS]

@@jacobvandijk6525 so when the cavity length accommodates an increment of half waves only then there will only be one or a few standing wave freq's? suppose it accommodated more than or less than half wave on the ends these will cancel the whole wave?

[@jacobvandijk6525]

@@ARCSTREAMS In theory, an infinite amount of frequencies is possible. But if you want light coming out of your laser, only the visible part of the EM-spectrum is relevant. And yes, only a part of all the waves survive and make a laser 'lase'.

[@MrPrimanshu]

thanks fr the explanation....nice work!!!

[@anonymus126]

Thx 4 uploading.

[@SahilMalik-zu8pe]

Just Perfect what else i could say👌

[@AhmedOsama_119]

Thank you

[@amrabdelfattah3528]

very nice thanks alot

[@delaramnematolahi1004]

Thank you :)

[@FabianMueller]

thank you!

[@HassanAlMusawi1975]

thanks

[@SudarakaMallawaArachchi]

Thanks :)

[@401jab]

Awesome! Perot is pronounced "Pear-oh" though haha

[@sabcam2000]

Just no. He has a decent "Perot" 's pronunciation. It's PE-RO or PA-RO (where A is pronounced like the letter A)

[@dreamlemonhope]

@@sabcam2000 I think he just wanted to note that the "t" is not pronounced (;

[@jacobvandijk6525]

Yep, just like Ross Perrot.

[@TheLightningStalker]

It's pronounced Parrow, not Pairit.

[@dileepk4024]

It is good that you found a terrible mistake which could shake the entire scientific community!!!

[@inventaunmanana4860]

now everything is wrong!!

[@mwerensteijn]

Thank you!

[@mucahitdemirc]
