Liquid Crystal Polarization Gratings (LCPGs) are highly efficient and versatile liquid crystal devices frequently employed in diverse technologies including light field regulation, beam polarization, and laser radar. A three-layer multi-twist structure of LCPG was prepared using a 266 nm laser interference exposure method, resulting in two types of LCPGs with periods of 7μm and 15μm respectively. Subsequent testing with a 1064 nm wavelength laser and comparison with simulations revealed that the polarization grating can sustain high diffraction efficiency within an incident angle of ±30° at the 1064 nm wavelength. This research paves a way for the applications such as laser radar and beam polarization.
