Front End Laser and Pump Diodes
Attached are 14-day plots from turning up the front end laser pump diode current(s) and adjusting their
temperatures.

Note that even though the NPRO output power plot reads that the NPRO power is ~0.81W.  As measured by a
power meter placed after the phase-correcting EOM, the power is 1.46W.  The NPRO power monitoring photodiode
measures the power into the power amplifier.

Diodes 1 & 2: 51 A -> 55 A
Diodes 3 & 4: 51.6 A -> 57 A

Diode 1: 17 degC -> 16.5 degC
Diode 2: 17.5 degC -> 16.5 degC
Diode 3: 18 degC -> 16.5 degC
Diode 4: 18 degC -> 16.5 degC
