Lasers: Power and wavelength dependence

  1. Jul 5, 2014 #1
    I have a 1550nm diode laser. I have a function generator sending a triangular function into the fast input of the laser; however, if I am within the bandwidth of the laser (under 10kHz), my output power of the laser mimics my fast input signal, so I get a triangular function on my O-scope with the same Vpp (typically 2V) and frequency. I wanted to know if there are any power stabilization techniques which will give me a DC signal on my O-scope.

    You are driving the laser diode with an ac drive waveform, and expect a dc output from your photodetector? What am I missing?

    Don't use an AC waveform to drive the laser?
