Abstract
The interaction of a high-intensity laser pulse with a plasma density channel preformed in a gas jet target has been studied. At neutral densities below 3.0 X 10(19) cm(-3) a strong interaction between the pulse and the channel walls was observed, there was clear evidence of pulse confinement, and the laser irradiance was significantly increased compared to an interaction with neutral gas. At higher gas densities, however, the radial uniformity and length of the channel were both found to be adversely affected by refractive defocusing of the prepulse used to generate the channel.
