The self-deflection of slab laser beams with right-triangular and semi-Gaussian intensity profiles that pass through a thin nonlinear film are compared, and semi-Gaussian beam profiles are found to produce near-maximum self-deflection angles. We also analyze symmetric profiles (both triangular and Gaussian), which, instead of self-(de)focusing, exhibit strongly counter-self-deflected beams in the far-field region. This evidence indicates that the self-deflection effect can dominate over self-focusing.
