Abstract
We have investigated the time constants of writing and decay of photor efractive gratings in 'blue' Rh:BaTiO3 at visible and near-infrared wa velengths. High reflectivity (> 200%) double phase conjugation has bee n achieved at near-infrared wavelengths (730-809 nm) and efficient dou ble colour pumped oscillation has been demonstrated between wavelength s separated by 150 nm.
