Characterization of a photorefractive Rhodium doped Barium Titanate crystal at 1,06 µm
Abstract : We characterize Rh:BaTiO, by cw two-beam coupling experiments at 1.06 µm. We demonstrate that all our measurements are well described by a single-carrier, single-site model as soon as the incident intensity is large enough. The effective trap density is found to be equal to N,, = 6 X 10^16 cm-3 and the maximum measured gain is 23 cm-‘. At 20 W cm-2 with a measured absorption of 0.15 cm-‘, the time constant is 75 s.
