摘　　要：实验研究了激光二极管抽运的Nd∶YVO4 环形单频激光器的强度噪声特性 ,通过光电负反馈调制激光二极管抽运源 ,使激光器的弛豫振荡噪声受到抑制 ,在 30 0kHz弛豫振荡峰处输出光的强度噪声被降低 2The 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.
