Not Enough Power for the SQZ SHG

After the laser power was reduced, there is no longer enough power coming out of SHG to deliver 20 mW into the fiber. This problem was compounded a few days ago when the offset to the power servo was reset to the wrong sign. Compared to the past, we currently run with about 70% of the power into the OPO (or ~14 mW into the fiber). The SHG output power currently reads about 26 mW when it was up 50 mW in the past. HW9 on ISCT6 needs to be adjusted.
