摘要:
Reduced KNbO3crystals are shown to have the fastest photorefractive response times for applications in the visible wavelength region. Grating build‐up times at cw illumination in the microsecond region are reported which allow the use of such crystals for real‐time applications. The reduction treatment and a new method for the investigation of the photorefractive homogeneity during reduction are presented.
