Abstract
Research on change of Rayleigh range ZR of output beams and effect of focusing characteristics caused by the dynamic process of resonator deformation especially for the HR coupler in high power CO2 Laser is given in this paper. An adaptive optics system which can compensates the change of Rayleigh range ZR was used. The real-time control of focus position was achieved.
