High-framerate pulse-to-pulse holographic beam-shaping using a ferroelectric liquid-crystal-on-silicon spatial light modulator

Over 1kHz reconfiguration of computer-generated holograms (CGHs) was implemented with a ferroelectric liquidcrystal- on-silicon spatial light modulator (FLCoS-SLM). The high-framerate reconstructions were performed on the 6.3 kHz pulse-to-pulse spatial light modulation. The reconfiguration speed will drastically change the applicability to science and industrial fields and open a door for new CGH applications. In this research, it was applied to parallel femtosecond laser material processing.
