本文分析了一种非传统的将激光器锁定在谐振腔中的方法。误差信号来源于腔基模与由模失配激发的二阶高阶空间模之间的干涉。该方案简单、廉价，并且与类似技术相比，一阶对光束抖动不敏感。在减轻技术噪声源之后，性能从根本上受到量子散粒噪声的限制。
We present the analysis of an unorthodox technique for locking a laser to a resonant optical cavity. Error signals are derived from the interference between the fundamental cavity mode and higher-order spatial modes of order two excited by mode mismatch. This scheme is simple, inexpensive, and, in contrast to similar techniques, first-order insensitive to beam jitter. After mitigating sources of technical noise, performance is fundamentally limited by quantum shot noise.
