✦ Synopsis

We report on the two-wave mixing of light in photorefractive waveguides in H ion-implanted Fe-doped near-stoichiometric lithium niobate crystals. For pump light of 632.8 nm wavelength a gain coefficient as high as 15 cm À1 is found. A response time of the order of a few seconds is achieved for micro-watt input powers.
