To determine incident laser power on a photodiode using the voltage from the photodiode (generally as measured with an oscilloscope), use:
<math> P=\frac{V
With <math>V</math> as the potential difference from the photodetector with the laser on/off, 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.
