Paper Abstract

The aim of this work was to investigate the conditions for waveguiding of nanosecond laser pulses in plasmas in microcapillary and gas jet for the development of a compact soft x-ray laser (SXL). A detailed study of He- and H-like carbon and nitrogen ion spectra, as a function of gas (plasma) densities, and plasma length was performed. The majority of the presented data were obtained in plasmas created in nitrogen injected into the vacuum chamber by pulsed electromagnetic valve. The waveguide conditions for the pump laser pulse (1.054 micrometer, 2 - 7 J, 1.5 ns) were achieved by line optical breakdown (up to 6 mm long) produced in gas by focusing a pre-pulse laser beam with an axicon lens. Intensive strong lines of H- and He-like ions were observed and the possibilities of obtaining the lasing conditions for SXL are discussed.
