Abstract

Two-beam coupling gain has been measured in Rh:doped BaTiO3 yielding a value of the order of 20,000. We believe that this is the highest beam coupling gain reported so far. Rh-doped BaTiO3 exhibits very strong intensity-dependent absorption, and this effect is considered when discussing experimental results.
