Replaced first filter (ND2) on S20 launch with an ND1 to use more of the cameras dynamic range.
Replaced DMNear ND (might be original ND2.6, but filters unlabeled) with an ND0.8 and a long tube to reduce the background noise. The waveplate in the DM Near/Far can now be left at 45deg for both the main and fiber laser. Added 2X ND0.3 to the flipper for high power operation.
Turned up SAGA voltages to get the main amp output back over 600mJ.

Adjusted main expanding telescope spacing from 120um to -440um to collimate the fiber laser in the tunnel. http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2023/38/19.09&pos=2023-09-19T23:55:40
