摘要

    摘要
  • 摘要: 针对实验中发现LD泵浦Nd∶YAG微片激光器的三类异常强度噪声，其强度波动幅度达20%~30%，严重影响了系统的稳定性，从理论和实验上对这三类强度噪声的特性进行了研究，包括外部光回馈引入的功率波动，LD异常噪声向固体激光器的传递，端泵浦偏离引起的模式耦合等。就各类噪声来源分别提出了相应的消除方法，抑制了微片Nd∶YAG激光器输出功率噪声，改善了激光输出特性，满足了频差精密测量的需要。
    Abstract: Three types of abnormal intensity noises of laser-diode(LD)-pumped Nd:YAG microchip laser were studied based on experimental data and theoretical analysis, including noises caused by the outside light feedback, the transmission of LD noise to solid laser and the mode coupling due to the deviation of end pumping. Corresponding methods were provided to eliminate these noises in order to suppress the intensity noise of the microchip Nd:YAG laser, improve the laser output characteristics and meet the demand of precision measurements.
