While scanning PMC, we noticed a large higher order mode. We went to SQZT0 and found that it was due to yaw misalignment. After we aligned PMC, we measured PMC input and transmission power. The PMC input power is 820mW and the transmission power is 680mW so the PMC transmissivity is 83%, which is much higher than before. We calibrated the SQZ-LASER_IR_DC_POWERMON and the SQZ-PMC_TRANS_DC_POWERMON to 820mW and 680mW, respectively. After we locked SHG, the SHG GR power reached 100mW.
We also put some beam dumps in SQZT0.
