Aligning a Scanning Fabry-Perot Interferometer

[@stanley6602]

Nice practice video. Step-by-step calculation and optical mounts setup make it easy to understand. Very useful👍👍

[@danjor50]

Incredible videos and alignment skills. Make more videos!

Yes he explained what he was doing so thoroughly.

Great video. Thanks!!! Waiting for the next one!

Could you please put the link for your other videos?

Do I know where to find these mirrors that semi reflective mirror? TY

[@mahdiassefzadeh6789]

Superb and great video! I'm aligning a THz semi-confocal cavity. Do you have any good resources for me? It's actually getting much harder than what I thought, and we don't have cameras for that. The only feedback from the cavity that I have is transmission, which is a single waveform/number vs. cavity length.

We have also buit scanning high finnese FPIs, we used cilindric piezos. The equipment on the base is fantastic. Where can I buy this.?

[@souvikbose1627]

Why do you use a beam folding technique????? Is it absolutely necessary??

[@souvikbose1627]

In the tutorial video of F-P, there are few errors in the draft. First, the X = 2d/cos(theta) instead of 2d/sin(theta). It doesn't affect the perfect transmission case because he assumes that X is a multiple of Lamba, therefore the phase factor drops off still giving the correct case of pure transmission. Second, Finesse is defined as 4r ^2/ (1- r^2), instead of 4r^2/ (1-r^2)^2! Apart from these two the video id good!!

Thank you for this informative vedio

Thanks for the video!

im looking for a fresnel lens , for laser project

Why do you choose 4 GHz as the FSR? If the FSR is 40GHz, it seems the experiment results will not change, right?

[@窦泽华]

Well I think the FSR is defined by the cavity length that is restricted by the focal length of mirrors. So in this video, FSR could not be 40 GHz.
