title: Amplification of optical signals in Bi(12)TiO(20) crystal by photorefractive surface waves.
abstract: We have demonstrated experimentally beam amplification by coupling between the signal beam and the photorefractive surfaces wave in Bi(12)TiO(20) crystal. A gain of 16,000 has been measured, with an output signal-to-noise ratio of >20 for weak input signals.
