With this set of measurement we should be able to grab power measurement from either ISCT6 or SQZT6 and figure out what goes into the OPO and what comes out of the OPO.
At the time 11mW was measured at ISCT6 input coupler. The SHG launch DC diode resistivity has been adjusted to agree with the measurement. From 0.192 A/W to 0.22 A/W. The change has been accepted in the SDF. BS reflectivity is 6.2%. So 6.2% of what SHG_LAUNCH_DC reads should equal to what goes in to the fiber coupler.
Green power measured at VOPO fiber was 3.3 mW (30% drop from ISCT6). 14% loss by the time the beam come out to the SQZT6 and hit the refl PD. Sheila believes this is due to the thin film polarizer.
The OPO refl diode calibration was fine tuned just today (resistivity was 0.22 A/W, now 0.21 A/W). It should reads 14% of what comes out of the OPO.
The measurement was taken while scanning the cavity at 1Hz.
After reading the BBPD design document more carefully I realized the DC transimpedance and responsivity is quite difference for green. The calibration has been changed to 0.3 A/W responsivity and 1400 Ohms transimpedance for the OPO green refl PD. V/W calibration here is still the same. SDF difference accepted.
