I measured the laser power at the base of the periscope this morning.  The power meter was located
in front of the mirror directing the beam upwards.

    With an Ophir PD300-3W-SH power meter (S/N 171141, P/N 1Z02411), the highest value measured
over a ~2 minute interval was 160.4 mW.

    With an Ophir 20C-SH power meter (S/N 1711175, P/N 7Z02602), the highest value measured over
a ~ 2 minute interval was 169 mW.

    Both readings were taken using a 10 second average, with the zero offset removed using the
Vega display unit.
