Paper Abstract

We reported the production of a plasma channel in a capillary discharge-produced plasma. Plasma parameters of its channel were observed by use of both a laser interferometer and a hydrogen plasma spectrum. A time-resolved electron temperature was measured, and its maximum temperature of 3 eV with electron densities of the order of 1017 cm-3 was observed at a discharge time of 150 ns and a maximum discharge current of 400 A. Intense laser pulse was guided over many vacuum Rayleigh lengths using its channel.
