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?
@@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. ruclips.net/video/saVE7pMhaxk/видео.html
@@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?
@@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'.
Very concise and to the point explanation! Loved it. Thanks for the video.
+Anantika Mehra I second that. I study a lasers-course at the moment and the video was helpful for understanding the class.
Great explanation. Just an idea - wouldn't it be even more effective if the mirrors focus the reflected photons?
could not get a better explanation...thanks a ton!! :)
Very simple and cool way of explanation. Thank you!
i'm an indian &i'm so thankful for your tutorial.i need it but its not sufficient.
Please have a seat right over there. - Chris Hansen
good one... can you please share passive mode locking of laser??

Very Nice Explanation !! Please upload the tuneable lasers using ring-resonators. Thanks
Nice explanation of F-P Laser.
It seems you have explained mode locking on an example of FP
could you help me out on how the fp laser connection works
Do you have an example of active medium? Thanks
For the very, very basics it's not a bad video.
Nice work!
Please produce more videos on optics. There are no new videos.
cant they make these diodes much bigger?
Very useful! Thank you!
Thank you great tutorial
so wont any cavity length work?
In theory, yes. As long as L = (1/2 wavelength) x any positive integer, and thus the bigger the integer, the smaller the wavelength.
@@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

Great explanations thanks!
thank you for this video...now i actually understood what is fp laser...thank you:)
very good explanation! thanks!
Nice explanation
Thank you. I wish you added more details. but still, appreciated
Hi there
I needed to learn some about fiber optics and fabri parot.
your videos helped me alot.
Thank you so much.
good luck
thanks fr the explanation....nice work!!!
Thx 4 uploading.
Just Perfect what else i could say👌
Thank you
very nice thanks alot
thank you!
Thank you :)
thanks
Thanks :)
Awesome! Perot is pronounced "Pear-oh" though haha
Just no. He has a decent "Perot" 's pronunciation. It's PE-RO or PA-RO (where A is pronounced like the letter A)
@@sabcam2000 I think he just wanted to note that the "t" is not pronounced (;
Yep, just like Ross Perrot.
It's pronounced Parrow, not Pairit.
It is good that you found a terrible mistake which could shake the entire scientific community!!!
now everything is wrong!!
Thank you!
thanks
