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.
