Vicky noticed that H1:SQZ-SHG_FIBR_REJECTED_DC_POWERMON is high, this is the rejected polarization polarization sent though the OPO pump fiber and measured in HAM7, trend over time attached.
Followed instructions in 71761 to reduce it from 0.55 to 0.03, plot. With ISS on, H1:SQZ-OPO_ISS_CONTROLMON is at 4.1V
With SQZ_OPO_LR in DOWN, H1:SQZ-OPO_REFL_DC_POWER increased from 2.2 to 2.3. Our maximum after on table AOM and fiber alignment is around 2.9V (last done August, September and November 74479).
