Frequency stabilization of a single-frequency all-solid-state laser for Doppler wind lidar

Abstract

The master laser of an injection-seeded laser for Doppler wind lidar is frequency stabilized to a Fabry-Perot (FP) cavity using Pound-Drever-Hall technique. The FP cavity is specially designed to gain high temperature stability with Zerodur cavity and spacer. A computer based controller is used to sample and process the error signal. After the master laser is locked. the relative frequency drift is +/- 25 kHz in 1 s. and +/- 55 kHz in 1 h. which can satisfy the need of Doppler wind lidar. 使用Pound-Drever-Hall技术将用于多普勒风激光雷达的注入式种子激光器的主激光器频率稳定到Fabry-Perot（FP）腔中。 FP腔经过专门设计，可通过Zerodur腔和垫片获得高温稳定性。 基于计算机的控制器用于采样和处理错误信号。 主激光器锁定后。 相对频率漂移在1 s内为+/- 25 kHz。 和+/- 55 kHz在1小时内。 可以满足多普勒测风激光雷达的需求。
