这篇文章先讲一下著名的用来锁激光的 Pound-Drever-Hall (PDH) 技术，然后再讲一个在此技术下导致激光频率变化的一个重要因素，以及如何去compensate掉这种影响。

2024年12月5日 · Abstract: The Pound-Drever-Hall (PDH) technique for laser linewidth narrowing is widely used by AMO experimentalists. However, achieving a high-performance PDH locking requires substantial engineering experience, which is scattered across literature and often lacks a cohesive control-theory perspective.

In this application note, we will describe a powerful and elegant technique, used in some of the most challenging precision measurements in modern optics, for controlling and stabilizing the frequency of a CW laser to a high-finesse optical cavity.

Presented are both a highlevel conceptual overview , discussing the general principles of operation, and a mathematical derivation of the linear, offsetdependent error signal used to stabilize the laser. Briefly covered are details of servo loops used to enact frequency locking, and various methods by which laser frequencies may be adjusted. 1.

2017年10月31日 · Here we report the demonstration of an integrated Pound−Drever−Hall system that can stabilize a low-cost laser to realize a compact inexpensive light source, which can ultimately impact many fields...

Abstract: The Pound-Drever-Hall (PDH) technique is a powerful method for laser frequency stabilization, and a PDH loop can also act as a single-channel sensor with high resolution and fast response speed. In this work, we expand the PDH technique into a time-domain distributed form, accomplishing a fast Brillouin optical time domain analysis ...
