Abstract
This paper describes a new approach for flattening high-power and high-gain CO2 lasers. A periodic change of curvature of concave mirror causes beam modes to jump in the course of time. Averaging out these beams results in an intensity profile with good uniformity. It is also compared to the output intensity ofthe resonator without vibration.
