==Notes== -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. *[https://wiki.physics.wisc.edu/yavuz/images/5/5b/Photodiode_%28Thorlabs_PDA36A%29_Calibration_for_all_Gains.pdf Voltage to Power Calibration]
