摘要
采用振幅调制器作为抑制激光强度噪声的元件 ,首先对光电负反馈回路进行了简要的理论分析 ,然后利用该光电负反馈进行抑制激光二极管抽运全固化单频环形Nd∶YVO4红外激光器强度噪声的实验。结果表明 ,在 0～1MHz的低频段 ,强度噪声大幅度降低 ,最大降低约
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.
