An improved cavitation model shows that stable beam channeling and electron cavitation occur for relativistic laser intensities even at powers hundreds of times larger than the critical power for self-focusing. Numerical calculations for long pulses (100 ps) demonstrate strong self-focusing at weakly relativistic intensities. The destructive effects of self-focusing are increasingly suppressed at high intensity. {copyright} {ital 1997 American Institute of Physics.}
