Optical beat note between diode lasers locked to ultra stable Fabry Perot resonators

[gamerU500]

Thank you for sharing the video . It is very interesting .I didn't reach this level ,still in school . The sub-atomic resonators , are they related to this resonator , or I'm I mistaken ? Just out of curiosity , what causes the sound every time you make something vibrate ?

Any help is appreciated :)

@gamerU500 Subatomic resonators have not heard about. There is subatomic resolution. 1 Hz laser means that mirror separation is held stable with 15 digits that corresponds to size of nucleus. This is possible because light averages over a large area on the mirror.

Vibrations change mirror separation. Mirror separation determines the optical resonance frequency of the resonator.

Electron cloud shape in atoms can have similar shape like light intensity inside the optical resonator.
