Abstract

Two-beam coupling has been studied at red and near-infrared wavelengths in blue Rh:BaTiO3. High amplification, of the order of 20,000–37,000, of a weak signal beam has been measured. The effect of strong intensity-dependent transmission is considered when theoretical plots are fitted to the experimental data.

Temporal evolution of the two-beam coupling signal. The measurements of three traces were separated by several minutes, and different light exposures were used before measurements: trace 1, long preillumination with light (5 min); trace 2, short preillumination with light (1 min); trace 3, no preillumination with light (10 min in the dark).
