LCLS lasers replaced the oscillator with a new one 12/15/2023. The Regen was tuned up with the new oscillator.

Wired up the S20 Launch mirror to the laser room picomotor controllers, the task was made difficult by a bunch of bad picomotor extension cables in the trailer. The picomotor now appears in the laser control panels for S20Launch http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2023/49/06.12&pos=2023-12-06T16:07:12
Replaced failed picomotor in B2. http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2023/49/05.12&pos=2023-12-05T10:51:10, http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2023/49/06.12&pos=2023-12-06T11:18:17

Realigned the laser to all irises. Reset auto aligner target positions to match the nominal alignment through the irises. Changed the auto aligner to only use MainampNear in the auto aligner. http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2023/45/09.11&pos=2023-11-09T22:47:29

Used the DM to adjust the collimation of the laser which seems to have changed after the oscillator was fixed . http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2023/44/03.11&pos=2023-11-03T23:55:51
- Note from the future: In later shifts, we went back to the flat in the tunnel actuator position and the beam looked collimated on CompFar. This was likely a B-integral effect.
LCLS lasers fixed the oscillator which had dropped out of modelock. http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2023/43/27.10&pos=2023-10-27T23:30:58
