Abstract
We determine, by a photoinduced light scattering study, that the incre ase of photorefractive sensitivity of the proton exchange waveguides i n lithium niobate crystals is more than 3 orders of magnitude as a res ult of copper doping under certain conditions. This increase is determ ined to be due to the nonphotovoltaic contribution to photorefraction with a short responsiveness time.
