Gain measurements at 18.22 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 microm) on a solid carbon target. The maximum gain measured was 8 +/- 2 cm(-1) in the recombining plasma column, with additional radiation cooling, with additional radiation cooling by iron impurities.
