| Abstract: | We report guiding of sub-100-fs pulses at intensities up to 5x10(15) W/cm (2) over a distance of 1 cm in a preformed plasma channel. The width of the guided pulse was shortened, which we attribute to ionization-induced refraction at the channel entrance. A pulse energy throughput of 30% in the lowest-order was measured. |
