Near-infrared incoherent coupling and photorefractive response time of 'blue' Rh:BaTiO3

[摘要] We have investigated the time constants of writing and decay of photorefractive gratings in 'blue' Rh:BaTiO3 at visible and near-infrared wavelengths. High reflectivity (> 200%) double phase conjugation has been achieved at near-infrared wavelengths (730-809 nm) and efficient double colour pumped oscillation has been demonstrated between wavelengths separated by 150 nm.
