We experimentally demonstrate the possibility of photorefractive 2D self-focusing in bulk Cerium doped Strontium Barium Niobate (SBN:Ce) directly at telecommunications wavelengths (1.06 μm and 1.55 μm). Although the electro-optic coefficient of SBN is smaller at infrared wavelengths, 2D infrared self-trapping is observed and analyzed versus different parameters such as the laser beam intensity, the external applied electric field and time.
