Abstract

Interferometry of plasmas generated by fast discharge excitation of Ag2S microcapillary channels shows the formation of dense plasma waveguides capable of guiding intense laser beams. Discharge ablation of capillaries, 330 μm or 440 μm in diameter, with 3-5.5-kA current pulses formed concave plasma density profiles with axial electron density >1 × 1019 cm-3. These dense plasma waveguides containing highly ionized metal atoms are of interest to the development of a longitudinally pumped soft X-ray lasers.
