We report on the first observation, to our knowledge, of self-focusing without an external electric field in barium titanate crystals under cw laser beam irradiance. This effect we observed at an intensity of 0.2W/cm2 on the 633nm wavelength regime in the case of ordinarily as well as extraordinarily polarized light.
