Laser trip
Came into the Control Room this morning to find that the laser had tripped off from the power watchdog.  Looking at
the trend data suggested that it tripped around 2:30 am.  Had some minor problems bringing the laser back on, whereby
the Beckhoff computer was not responding.  Opted to reboot the computer.  It came back without any problems.  The
laser restarted okay afterwards, with the output power considerably down from yesterday (as indicated on the main
user screen).  I opted to increase the diode currents.

    The  power watchdogs are currently OFF.
