A PLCX-25.4-64.4-UV-1064 (f = 143.23 mm) lens was placed in the path at z = 1247 mm. The order of components after the AEOM was (Space for waveplate)->PBS->Steering Mirror->Lens->lambda/2->EOM2. The lens placement was very clost to the steering mirror, but it was difficult to find a choice of lens that would accommodate a suitably focused solution.
This final EOM (before the PMC) was placed at z = 1440 mm (ref. to laser head position).
The beam was profiled after the EOM2 to get better characteristics for MM to the PMC. The fit was:
Horz. beam waist = 246.0624 um
Horz. beam waist position = 1397.5481 mm
Vert. beam waist = 210.7356 um
Vert. beam waist position = 1252.1215 mm
The waist was set a little bigger to ease the MM placement sensitivity of the first lens for matching into the PMC. Data and plot attached.
Next MM to the PMC (although this wont be put in place until after we have gotten a first beat note).
