Self-focusing of cylindrical beams due to the ponderomotive force behaves quite differently for the full exponential nonlinearity than for the weak, cubic-nonlinearity limit. Steady self-trapped propagation becomes possible for arbitrary incident powers. Self-focusing becomes a periodic oscillatory phenomenon, rather than a catastrophic process in which the light intensity increases without limit. (AIP)
