摘要：

Holograms may be recorded in photorefractive LiNbO3:Cu with pulsed infrared light (wavelength lambda = 1064 nm, Q-switched Nd: YAG laser), if the crystals are previously or simultaneously illuminated with a green (lambda = 532 nm) light pulse. We study refractive index changes and time constants of as-grown and thermally treated crystals with different copper concentrations. A model explaining this effect is discussed.
