Abstract
Efficient internal-loop self-pumped phase conjugation is demonstrated in a photorefractive rhodium-doped barium titanate crystal by repetitively pulsed nanosecond pulses from a -switched Nd:YAG laser operating at . Phase-conjugate reflectivities as high as 32% are obtained with a response time of at a repetition rate of 30 Hz. The ability of the phase conjugator to correct severe phase distortions is also demonstrated.
