Abstract

Recombination-pumped soft-x-ray laser experiments are performed with a novel target consisting of an array of thin fibers. Laser plasmas produced from such targets are shown to be capable of producing a broad region of relatively high gain. Gain coefficients for the C Balmer α line of $4 {\mathrm{cm}}^{-1}$ are observed over a wide spatial region spanning 300 µm for targets with fiber spacings of 100 µm.
