Abstract

The laser output power stability is one of the most important parameters to evaluate a laser performance. Both the operation principle and the structural features of a laser-diode (LD) end-pumped single-frequency Nd:YAG laser at 1064nm are described, the main factors that affect the stability of Nd:YAG laser output power are recieved, and a control scheme has been proposed and experimentally studied for the stabilization Nd:YAG laser output power. Because the output power of Nd:YAG laser is proportional to the injection current LD when the temperature of LD and Nd:YAG crystal rod is stable, the control scheme requires firstly that the temperature of LD and Nd:YAG crystal rod be strictly controlled, then LD's injection current be adjusted throng a negative feedback control system when Nd:YAG laser output power fluctuates. Experimental results indicate the laser output power stability is better than 1.3% within a period of 130 minutes by use of the designed control system when the output power of LD-pumped single-frequency Nd:YAG laser at 1064nm is about 11.5mW,
