Abstract
A hydrodynamic simulation is used to show that intense laser pulses pr opagating in underdense plasmas create stable, long-lived, and complet ely evacuated channels. At low intensities, I=10(17) W/cm(2), self foc using seriously distorts the temporal envelope of the pulse, but chann eling still occurs. At high intensities, l=10(19) W/cm(2), channeling can proceed over many diffraction lengths with significant distortion restricted to the leading edge of the pulse.
