Abstract

We demonstrate a photorefractive incoherent-to-coherent optical converter using anisotropic self-diffraction (ASD) in BaTiO₃. Only two writing beams are required in the spatial light modulator and no extra readout beam is required. The diffraction efficiency reaches 50 percent. The resolution diffracted image is 22.6 lp/mm with a 6.6 by 6.6 by 7 mm crystal. We can increase the resolution by using a thin crystal without expense of the diffraction efficiency because of the inherent high diffraction efficiency of ASD in BaTiO₃.
