Improvement of the beam quality of a wave-front dividing beam combined laser system using a serrated aperture

Abstract

A numerical calculation of a serrated aperture for the wave-front dividing beam combined laser system has been done. The concerned variables are the length of the tooth, the number of the teeth, and the ratio of the diameter of the spatial filtering hole to the focal length of the lens. From the simulation result, the variables of the serrated aperture for the wave-front dividing beam combined laser system are determined.
