Abstract

In order to stabilize the output frequency of 1064nm single frequency fiber laser, the Pound-Drever-Hall(PDH) locking technique was applied for laser frequency stabilization. The PDH optical heterodyne frequency stabilization system was established. The phase modulation optical heterodyne signal and the demodulation error signal were analyzed. Field-programmable gate array(FPGA) based digital PDH demodulation and feedback control system was designed. A sine wave generator and the multiplication demodulation were implemented in FPGA. Then the error signals were obtained by digital/analog convector. Experimental results show that phase modulation optical heterodyne signal is demodulated successfully in FPGA, and the Allan variance of frequency drifts can reach 10-11, a high level of frequency stabilization.
