At a non-linear gain of ~2.3 is where I believe we were operating during O3a. Lee accidently made the range better with normalized OPO transmission of 1 but forgot to adjust the temperature to optimize the nlg, this could mean we are better off operating at low pump power. The pump power is now set to NLG of 2.5. This corresponds to the normalized transmission value of 0.67, pump input to the coupler is 7.3mW, 3.8mW reflected when OPO is unlocked. To be able to engage the OPO ISS I had to throw away about half the power with the half wave plate.

Let's start SQZ optimization from here.
