Laser Beam Shaping Using Liquid Crystal Spatial Light Modulator
A new method for real time and controllable laser beam shaping using liquid crystal spatial light modulator (LC-SLM) is presented. The optical modulation characteristics of LC SLM are studied. An optical system that consists of a soft edge serrated aperture formed by LC SLM and a filter could effectively convert an arbitrary profiles beam into a flattop intensity beam with a high fill factor in the near field.
