Abstract
Adaptive optics has been successfully used in astronomy to obtain near diffraction limited images. It also can be used to improve the laser beam quality. In this paper, a test that a He-Ne laser was used to simulate an annular beam and was cleaned up by the 61 elements adaptive optical system is reported. The results show that the beam quality is improved.
