Phase reflective OA LC SLM with the clear aperture up to 50-mm for recording dynamic holographic grating with high-diffraction efficiency

The results of experimental and theoretical studies are presented on the development of optically addressed liquid crystal spatial light modulators (OA LC SLM) with clear aperture up to 50 mm and phase modulation depth up more than 2π. The optimization of electrical and optical characteristics of liquid crystal, photoconductor, dielectric mirror and blocking layers resulted in fabrication of samples of OA LC SLM that allowed writing diffraction gratings with the phase amplitude up to 2π and variable profile of grating fringes.
