The spatial shaping of light beams is the process of redistributing the irradiance of a light beam. A correct beam shaping is essential to optimize a large number of laser-material processing applications and laser-material interaction studies. In this paper, after introducing the basic equations of the classical beam integration method to reshape and homogenize laser beams, we detail the design elements, the experimental performance and the main parameters of a novel transfocal homogenizer that is able to homogenize and reshape any light beam. Then we discuss the reliability of existing international standard parameters to evaluate the “goodness” of nearly flat-top shaped laser beams. Finally, we present examples of successful applications of this new homogenizer technology to ultraviolet irradiation experiments.
