To determine laser power:
[math]\displaystyle{ P=V/((Amps/W * (V/Amps)) }[/math]
With [math]\displaystyle{ V }[/math] as the measured voltage from the photodetector, and [math]\displaystyle{ Amps/W }[/math] and [math]\displaystyle{ 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).
