Oli, Camilla (Oli did the work, I just wrote down what they did!)

Oli had been troubleshooting SQZ and found that when the OPO ISS tried to engage, it go to 10V and then unlocked. The OPO Trans output was only ~50uW on LOCKED_CLF_NO_ISS. This was meaning the ISS was maxing out it's 0-10V range to get to the nominal setpoint of 80uW. 

We could see on SQZT0 medm that the SHG output power was 81.2mW when nominal is ~ 100mW. This will reduce the available power to the OPO path. We followed the wiki to increase the SHG power (I should make the instructions of when to do this clearer) by adjusting the SHG SETTEMP. Doing this, Oli brought SHG power up from 81mW to 92mW. 

Then the OPO Trans output was ~65uW on LOCKED_CLF_NO_ISS (nominal 80uW). So Oli moved the waveplate between the +200MHz AOM and the SHG Rejected PD in the "to OPO" path to increase the available power sent into SHG launch. Then the AOM had enough range and the OPO could lock in LOCKED_CLF_DUAL_NO_ISS. 

Then Oli had issues with getting the FC to lock in Green so followed the wiki instructions to in do that too, trending to last good alignments with ZM3 (had moved 20urad on FC lockloss from ASC turning off) and then manually locking FC and increasing power with FC2, (FC1, ZM3) alignments. Oli increased the power in the 0,0 mode form 35 to 65 with alignments. Nominally this is > 80 but it had only been at 50 in the last lock, probably from the SHG power being low.
