Abstract
The nonlinear response of photorefractive crystals at wavelengths around 1.3 and 1.5 µm is of importance for applications in all-optical telecommunication systems. However, in general most photorefractive crystals are sensitive only for visible light. First attempts to extend the nonlinear response up to 1550 nm have been made in KNbO3 [1]. In our contribution we investigate the properties of strontium-barium niobate (SBN) crystals in the near infrared up to telecommunication wavelengths.
