Abstract
We report guiding of sub-100-fs pulses at intensities up to 5 x 10(15) W/cm(2) over a distance of 1 cm in a preformed plasma channel. The wi dth of the guided pulse was shortened, which we attribute to ionizatio n-induced refraction at the channel entrance. A pulse energy throughpu t of 30% in the lowest-order was measured.
