Characterization of photorefractive properties of 'blue' Rh:BaTiO<sub>3</sub> via nonlinear wave mixing

We have investigated the ability of Rh:BaTiO<sub>3</sub> to couple and diffract light via electro-optic and absorption gratings. The photorefractive two-beam coupling gain we observed was very high, showing the potential of this crystal to efficiently amplify weak signals. Also, to estim...

Description
Summary:We have investigated the ability of Rh:BaTiO<sub>3</sub> to couple and diffract light via electro-optic and absorption gratings. The photorefractive two-beam coupling gain we observed was very high, showing the potential of this crystal to efficiently amplify weak signals. Also, to estimate the strength of the gratings formed during beam coupling, we have measured diffraction efficiency, which was as high as 80%. Additionally an improvement in the response time, as compared to an undoped BaTiO<sub>3</sub> crystal was observed.
