modulate frequency and check the reflected beam power

Nishino,Mitsuhashi,Shalika

What we did:
We modelated a lazer frequency to observe the resonance of the cryogenic cavity, and checked the reflected beam power.
As a result, we can't observed the resonance of the cavity at all.
The picture of a oscilloscope was attached when we modulated a lazer frequency. The blue line is the reflected beam power.


What we will do next:
We optimize the mirror angle and the lens position.
