Abstract

High-power CO2 laser beam intensity distribution is nonuniform, which is caused by inhomogeneously gain medium. Aiming at that nonuniform distribution, a new resonator consisting of a roof mirror is designed. At the same time the beam intensity distribution is modified to obtain greater temporal uniformity by reflector's periodically vibrating. Output modes of both the resonator with a pair of parallel-plane mirrors and the former new resonator are obtained by numerical simulation calculation with Fox-Li iteration. Simulated results are presented that with the resonator uniformization ofthe beam intensity distribution can be achieved.
