abstract = {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.}
