摘要
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.
