J. Zhang et al., CHARACTERISTICS OF RAPIDLY RECOMBINING PLASMAS SUITABLE FOR HIGH-GAINX-RAY LASER ACTION, Laser and particle beams, 14(1), 1996, pp. 71-79
Recombining plasmas produced by picosecond laser pulses are characteri
zed by measuring ratio of intensities of resonance lines of H- and He-
like ions in the plasmas. It is found that the rapidly recombining pla
smas produced by picosecond laser pulses are suitable for high-gain op
eration.
