Abstract
It is shown that thermally fixed photorefractive gratings fabricated for waveguide lasers in Ti:Fe:Er:LiNbO3 can be refreshed and stabilised by the upconverted green fluorescence from Er3+ ions. Spectral properties of such refreshed gratings are found to be superior and are excellent for a single-frequency laser emission.
