%X The optical pulsation phenomenon which occurs in two-beam coupling and four-wave mixing in photorefractive LiNbO_3:Fe crystal is reported. This phenomenon is considered to originate from the trap-recharging wave in LiNbO_3:Fe crystal, which induces a moving phase grating in the photorefractive material.
