Abstract

Results of the experimental analysis concerning the output beam characteristics of the industrial cw CO₂ laser with an intracavity deformable mirror are presented. The mirror used is a bimorph piezoelectric adaptive mirror developed at Turn Ltd (Russia). The mirror shape is controlled by supplying the voltage to the mirror electrodes. The performed analysis proves that the use of the deformable mirror with a variable radius of curvature in the laser cavity enables controlled and dynamic changes of the resonator properties that result in the modification and optimization of the laser output characteristics decisive for the laser material processing effects.
