The experimental observation of photorefractive self focusing in Sn(2)P(2)S(6) : Te bulk crystals at 1.06 mum wavelength is presented. Steady state self focusing is reached as fast as 15 ms for an input peak intensity equal to 160 W/cm(2). Self focusing is maximum for input peak intensities around 15 W/cm(2) and is decreasing for intensities below and above this value.
