In order to solve the problem of the output beam offsets induced by assembling and heat distortion of mirrors in radio frequency slab CO 2 lasers, offsets were compensated by means of the outside optics .An offset compensation device was designed based on piezoelectric ceramics .Piezoelectric ceramics actuators were designed and the control accuracy and adaptive control method were analyzed .The results show that laser output power at any duty ratio can meet or exceed the standard reference power value after compensation .The maximum difference of output power is 100W before and after adaptive regulation and the laser output power fluctuation is less than 2%during the running of 2h.The output beam compensation can ensure laser run efficiently , increase the stability of laser power and laser mode .The research has the high practical value .
