We report, for the first time to our knowledge, on picosecond-pulse optical phase conjugation using photorefractive Sn2P2S6 crystals. For 7.2-ps pulses at 1.06 μm, we have achieved phase-conjugate reflectivities of up to 45% with very fast build-up times, about 15 ms at an intensity of 23 W/cm2 using Te-doped Sn2P2S6. We furthermore demonstrate aberration-free 5 W optical output of 8-ps pulses at 1.06 μm from a side pumped Nd:YVO4 amplifier using the Sn2P2S6-based phase-conjugate feedback.
