Abstract
We examine a scheme for a compact nickel-like tungsten soft x- ray laser operating on the 4d - 4p, J equals 0 - 1 transition at 43.2 angstrom. High gains are achieved by operating at high electron densities (ne greater than 1022 cm-3). In this regime, the gain during non-equilibrium ionization can greatly exceed that of the steady state. The duration of this transient gain is on the order of the ionization time which makes picosecond-pulsed optical pumps ideal. We predict gains of 220 cm-1 for a 1 micrometer pump of intensity I equals 1 X 1017 W/cm2.
