Paper Abstract

A offset frequency lock system is used for I 0. 6jim laser heterodyne frequency tracking. The system uses digital offset-lock servo loop to realize the offset frequency lock of the tracking laser to the reference one. With computer realtime processing the offset frequency stability of 1 O 1 012is got by nieasurement of Allan variance at different sample times. The tracking range is 45MHz(when offset frequency is 32MHz)and the capture range is about 65MHz. The system shows an excellent anti-interference ability and a high stability.
