Abstract

Photorefractive materials offer great promise for applications in adaptive optics and optical data processing using degenerate four-wave mixing (DFWM). BaTiO3 is a particularly promising material, primarily because the very large value of the electrooptic tensor component r42 yields correspondingly large values of grating efficiency, beam coupling gain, and DFWM reflectivity.
