Beam shaping of high power diode laser stack into homogeneous line

Abstract

In this paper, analysis of beam shaping and homogenization of high power diode laser stack into a line focus with dimension of 10 mm × 0.5 mm was reported. The beam shaping and homogenization was simulated by using ZemaX-ray tracing technique. The results have shown that intensity distribution after beam shaping and homogenization at the work piece is a flat top for the slow axis with homogeneity over 95% and a Gaussian distribution for the fast axis.
