I optimized mode matching for RCAV. The coupling is ~75%. I also minimized RFAM from the 35.5MHz EOM.
For RCAV mode matching, I moved only two lenses in front of RCAV (R=51.5 and 20.6 mm) to optimize the mode matching.
I have not tried moving other lenses or the mirror behind AOM yet, because I think 75% is enough for now.
The reflected beam will cause the shot noise level to be higher, but it should not be critical for our current situation.
