Near-infrared incoherent coupling and photorefractive response time of 'blue' Rh:BaTiO3
Optics Communications, 136, . (doi:10.1016/S0030-4018(96)00687-6).
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
