-To determine laser power:
<math> P=V/((Amps/W) * (V/Amps)) </math>
With <math>V</math> as the measured voltage from the photodetector, and <math>Amps/W</math> and <math>V/Amp</math> as two conversion factors depending on the wavelength of the laser and the gain setting of the detector respectively (page 9 and 11 in user manual).
-Response is consistent from photodiode to photodiode.
-Zero point can shift a few tenths of a millivolt depending on the temperature.
