Abstract:Aiming at improving the beam quality of thin-wall tube laser, a novel method based on the right-angle cone deformable mirror is proposed. In the method, a reflector with inner right-angle conical surface is used, and the annular laser beam successively passes through the opposite sides of the tube, compensating for the off-axis aberrations of the annular laser beam. Next, the residual aberrations are corrected by the deformation of the right-angle cone mirror to further improve the beam quality. The physical m… Show more
