Paper Abstract

Mn:Fe:LiNbO3 crystals were grown using the conventional Czochalski method. The phase conjugate reflectivity and response time were measured by four-wave fixing method with Ar+ laser (488nm) as light source. Non-degenerate phase conjugate wave varying frequency was obtained in Mn:Fe:LiNbO3 and Fe:LiNbO3 crystals with Ar+ laser (488nm) and He-Ne laser (632.8 nm) as light source. The maximum of phase conjugate reflectivity varying frequency of Mn:Fe:LiNbO3 crystal was up to 920%, three orders of magnitude than that of Fe:LiNbO3 crystal. Based on Li vacancy model, we discussed the photorefractive improving mechanism of Mn:Fe:LiNbO3 crystal.
