摘要：
We report a method to stabilize the frequency of a laser diode for a long time by means of four feedback loops including a digital feedback circuit. The laser frequency was locked at a saturated absorption peak of cesium atoms. In addition, by feeding back the frequency error signal to the temperature controller of the laser diode, the power as well as the frequency was stabilized at the same time. The power stability of 0.03% was obtained, which was 260 times better than that obtained without the feedback. The frequency stabilization continued for over 1 week and the fluctuation width was about +/- 0.5 MHz around the locking point. (C) 1996 American Institute of Physics.
