Abstract:
A hydrogen plasma waveguide for high-intensity laser pulses is described. The guiding channel is formed by a small-scale discharge in a hydrogen-filled capillary. The measured lifetime of the capillary is inferred to be greater than 106 shots. The results of interferometric measurements of the electron density in the capillary are presented. The guiding channel is found to be highly ionized with an axial electron density of 2.7 ×1018 cm-3, and parabolic, the curvature corresponding to a matched spot-size of 37.5 μm. ©2000 The American Physical Society.Investigation of a novel hydrogen plasma waveguide for high-intensity laser pulses

Abstract:
We present measurements of the electron density profile in the guiding channel of a novel plasma waveguide. The results of experiments to demonstrate guiding at peak intensities of >10−17 W cm−2 will be presented.Investigation of a hydrogen plasma waveguide.

A hydrogen plasma waveguide for high-intensity laser pulses is described. The guiding channel is formed by a small-scale discharge in a hydrogen-filled capillary. The measured lifetime of the capillary is inferred to be greater than 10(6) shots. The results of interferometric measurements of the electron density in the capillary are presented. The guiding channel is found to be highly ionized with an axial electron density of 2.7x10(18) cm(-3), and parabolic, the curvature corresponding to a matched spot-size of 37.5 microm.Inner-shell soft X-ray lasers in Ne-like ions driven by optical field ionization
