The first EOM was placed at the waist along with PBS and wave plates in the order lambda/4-lambda/2-PBS-EOM-lambda/2.
The beam was reameasured after this point (as a check). Fit was:
Horz. beam waist = 176.5893 um
Horz. beam waist position = 780.5592 mm
Vert. beam waist = 94.6329 um
Vert. beam waist position = 811.292 mm
Next we place a PLCX-25.4-46.4-UV-1064 (f = 103.20 mm) for next alignment into AEOM. |
