Abstract

The widespread use of lasers in technological processes highlights the problem of controlling the laser beam parameters. For example, metal-cutting processes typically demand the tightest beam focus possible. 1 On the other hand, metal-hardening processes require a laser beam with the most uniform transverse irradiance distribution possible. 2 For several laser applications in material processing and manufacturing, nonlinear conversion of a laser beam to a shape with uniform rectangular crosssection is often desirable. 1, 2 Examples of such uniform beams include highly multimode laser beams, 3 flattened Gaussian beams, 4, 5 and super-Gaussian beams. 6, 7
