Abstract

Experimental demonstration of optical guiding of a high intensity (above 1016w/cm2) laser pulses over a distance of 66mm in cylindrical plasma channel formed by a slow capillary discharge is presented. Optical guiding of high intensity pulse in a curved trajectory (radius of curvature = 10 cm) is demonstrated for the first time. It is shown experimentally, that the guiding is insensitive to the laser intensity in wide range (108-1016w/cm2). The propagation of a high intensity laser pulse in the channel is analyzed using 2-D numerical simulation code.
