Laser Turn on report
When the laser was first turned on (slowly, as per the manual), the output power was only ~14 W instead of 35.
Some tweaking of the mirrors M4 & M5 (~1 full turn each in both pitch and yaw) restored the power. The peak
power was 37.0 W
as measured on the Big Head.
The beam is also not centered on the monitor PD and so its more likely a small shift of some earlier
mount than such large shifts of those last two mirrors.
With the cold temperature, the power has
drooped to 35.5 W
