Preliminary study on the compensation of the wavefront deformation inducedby freevortex aerodynamic window using AO system

The freevortex aerodynamic window(FADW) can take the place of the conventional crystal output window sealing the lower pressure laser cavity of high energy lasers effectively. But the supersonic flow of the FADW will introduce some deformation to the output high power laser beam so it is necessary to compensate the disturbed laser beam using the adaptive optical system. This paper studies the compensation of the wavefront deformation of the FADW under the ideal designing situation using the 37 subapertures indoor adaptive optical system.It discusses the principle of the adaptive optical system and gives the experimental method and compensaton results. The results show that this 37 subapertures indoor adaptive optical system can compensate the wavefront deformation of the FADW under the des
