[Daniel, Torrey]

-We moved the AOM RF power drive to moku 4 channel 4. A 10 db attenuator is on the end of it and the amplitude coming out of M4CH4 is maxed (2 Vpp) which yields 632mVpp the previous drive amplitude was 600 mVpp. This should functionally limit the AOM being destroyed, outside of turning the channel output to +14dB mode.

-We put a large scan amplitude into the laser frequency to see multiple FSRs on the 775 path. We then measured the difference between the FSRs and they disagree by 0.4% in one measurment and 0.8% in another. The scan was ~1 Vpp.

Some future steps:

Calculate 775 nm finesse with ring down using AOM

Look at 1550 nm transmission using 775 nm lock when the 1550 nm light is resonant and half way between resonances

Calculate 1550 nm to 775 nm peak drift using PDH error signal of 1550 nm light. Likely requires better 775 nm lock
