This morning I tweaked up the PSL PMC alignment remotely using the picomotor-controlled mirrors with the ISS off. I was only able to get about 60mW of power increase out of the PMC, but I decreased reflected power by about 200mW, so perhaps there's some mode-matching that could be optimized in the future.
After that, I recalibrated the rotation stage using the following process:
Power in (W) | D | B (Minimum power angle) | C (Minimum power) | |
Old Values | 103.151 | 1.990 | -24.823 | 0.000 |
New Values | 102.287 | 1.990 | -24.825 |
0.000 |
