Abstract

Self-pumped phase conjugation in Ce-doped barium titanate crystal is investigated with 1-Hz-repetition-rate nanosecond pulses from a Q-switched frequency-doubled Nd:YAG laser (532 nm wavelength). Phase conjugate reflectivity as high as 21.5% are obtained at an incident angle of 500. Dark storage time, defined as the time after which the phase conjugate reflectivity declines to 90% of steady-state value when photorefractive crystal is in dark condition, is more than 20 minutes. Furthermore, self-pulsation of SPPC energy is studied.
