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 (n_e 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.
