Gain measurements at 1822 nm in C vi generated by a Nd:glass laser

Abstract
We present recent gain measurements in C vi at 18.22 nm for a soft-x-ray amplifier produced by a line-focused glass laser (1.053 μm) on a solid carbon target. The maximum gain measured was 8 ± 2 cm−1 in the recombining plasma column, with additional radiation cooling by iron impurities.
