PMC trans was only ~0.79, where it should be ~0.84 something. The MC was also not stellar.
I aligned the beam to the PMC, and am now getting PMC trans 0.837 .
Then I aligned the PSL zigzag to the MC, and got MC Refl down to ~0.6 .
I then aligned the WFS to the unlocked MC, and the MC Trans QPD to the locked MC.
Things seem good. MC axis is still in a good place, since we get good michelson fringes at the AS port. |
