  • High laser damage threshold reflective light addressing liquid crystal spatial light modulator for linearly polarized light at 1053 nm
    Patent number: 11543692
    Abstract: A high laser damage threshold reflective optically addressed liquid crystal spatial light modulator for shaping 1053 nm linearly polarized light beams, comprising a computer-controlled LCoS electrical addressable spatial light modulator, polarization beam splitter, and polarizer, Liquid crystal cell, analyzer, AC power supply, where the liquid crystal cell comprises a transparent conductive film antireflection film layer, a transparent conductive film base layer, a first transparent conductive layer, a liquid crystal alignment layer, a liquid crystal layer, an alignment element, a reflective film layer, a light guide layer, and a second transparent conductive layer. By changing the transparent conductive layer material of the light-transmitting part of the liquid crystal cell from ITO to gallium nitride material, the damage threshold of the high-energy laser is improved, which facilitates application of beam shaping in high-power laser devices.
