The characteristic of the intensity noise of LD pumped single frequency ring Nd∶YVO 4 lasers is theoretically and experimentally investigated. The resonant relaxation oscillation (RRO) in the noise spectrum of laser output is strongly suppressed by a self designed negatively opto electronic feedback system. The intensity noise around the peak of RRO (300 kHz) is reduced about 25 dB.
