开发了两个由高精度光学腔稳定频率的 1,064 nm Nd:YAG 激光器，用于研究超稳定光学振荡器中的各种噪声机制。使用单独的传感路径实现了剩余幅度调制的主动控制，并通过测量扰动激光器和稳定参考之间的光学外差差拍的抑制比，从理论上分析了其在存在谐振光学腔的情况下的有效性，并通过实验验证了其有效性。对源自振动、残余幅度调制、量子限制散粒噪声和电子噪声的激光频率噪声进行了实验分析。通过主动控制，残余幅度调制在 0.02–1,000 s 时被抑制到低于 1 × 10−6，在 ~2 s 时达到最小值 2 × 10−7。 0.1 至 10 s 的频率稳定性为 2 × 10−15，两个 Nd:YAG 激光器的光学外差拍频显示 1 Hz 线宽，测量时间为 4.096 s。此外，根据线宽与调制激光频率的潜在闪烁噪声之间的简化关系，实验确定的线宽与计算结果非常吻合。
Two 1,064-nm Nd:YAG lasers frequency stabilized by high-finesse optical cavities are developed to investigate various noise mechanisms in ultra-stable optical oscillators. Active control of residual amplitude modulation using a separate sensing path is implemented and its effectiveness in the presence of a resonant optical cavity is theoretically analyzed and experimentally verified by measuring the rejection ratios in optical heterodyne beat between a perturbed laser and a stable reference. Laser frequency noises originated from vibration, residual amplitude modulation, quantum-limited shot noise, and electronic noise are experimentally analyzed. With active control, residual amplitude modulation is suppressed to below 1 × 10−6at 0.02–1,000 s, reaching a minimum of 2 × 10−7at ~2 s. A frequency stability of 2 × 10−15is obtained from 0.1 to 10 s, and the optical heterodyne beat of the two Nd:YAG lasers shows 1-Hz linewidth with a measurement time of 4.096 s. In addition, the experimentally determined linewidths agree well with the calculation according to a simplified relationship between the linewidth and the underlying flicker noise that modulates the laser frequency.
