-To determine laser power:
With as the measured voltage from the photodetector, and and 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.
