Suppression of Intensity Noise by an Opto-Electronic Feedback Loop with Amplitude Modulator
An opto electronic feedback loop with AM was used to suppress the laser intensity noise. The opto electronic feedback loop was analyzed theoretically and then we experimentally suppressed the intensity noise of LD pumped single frequency ring Nd∶YVO 4 infrared laser by using the feedback loop. The result indicated that the intensity noise is reduced greatly between 0~1 MHz frequency with the maximum reduction 15 dB.
