摘要：

We characterize Rh:BaTiO3 by cw two-beam coupling experiments at 1.06 mu m 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-eff = 6 x 10(16) cm(-3) and the maximum measured gain is 23 cm(-1). At 20 W cm(-2) with a measured absorption of 0.15 cm(-1), the time constant is 75 s.
