【Abstract】 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.更多还原
