Optimization of static and linear beam pattern for laser surface modification

摘要

A novel beam optimization system, which provides static and linear beam pattern (SLP) for laser surface modification has been developed. Geometrical and physical theories were used to calculate the beam shaping distribution. The laser pattern experiment with the system has been made. It was shown the laser intensity distribution in the linear pattern was uniform, and the SLP widths can be adjusted from 15 to 25 mm continuously.
