Notes

-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.
