Other AbstractFor a high power CO_2 laser, its work medium and resonator components including mirrors and coupler will be distorted under condition of high power laser output. Although with various cooling methods for the resonator, the distortions always happen under different output powers. It means the Rayleigh range Z_R of the certain resonator is varying under different output power. The change rule of Rayleigh range Z_R of output beams caused by the output coupler thermal deformation at various output power are researched. An adaptive optics system, which can compensate the change of Rayleigh range Z_R and revises the effect caused by the thermal distortion of the output coupler, was used. Good focusing characteristics in flying optics is achieved in this way.
