摘要：

A hydrodynamic simulation is used to show that intense laser pulses propagating in underdense plasmas create stable, long-lived, and completely evacuated channels. At low intensities, I=10(17) W/cm(2), self focusing seriously distorts the temporal envelope of the pulse, but channeling 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.
