TL;DR: For the first time to the authors' knowledge, on picosecondpulse optical phase conjugation using photorefractive Sn(2)P( 2)S(6) crystals, phase-conjugate reflectivities of up to 45% with very fast build-up times are achieved.
Abstract: 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.

TL;DR: In this article, the effect of coherence between pump and signal beams on phase conjugation by degenerate four-wave mixing is analyzed using a simple classical model and the influence this may have on practical applications is discussed.

TL;DR: In this article, the authors demonstrate polarisation insensitive dual-band optical phase conjugation for multiple 400Gbit/s optical superchannels using a Raman amplified transmission link with a realistic span length of 75km.
Abstract: We demonstrate polarisation insensitive dual-band optical phase conjugation for multiple 400Gbit/s optical superchannels using a Raman amplified transmission link with a realistic span length of 75km. The resultant increase in transmission distance is confirmed analytically.

TL;DR: In this article, a stable-state solution to generalised two-cell stimulated Brillouin scattering systems is presented, including consideration of additional attenuation placed the two cells for extra protection of the small aperture generator cell from high laser power density.
