Abstract

A Ne-like TCE (transient collisional excitation) x-ray laser at 19.6 nm (J equals 0 implied by 1, 3p implied by 3s) was investigated numerically using a sophistic hydrodynamic code for a 100-micrometers thick Ge planar target irradiated by a nano- second prepulse followed by a picosecond main optical laser pulse. The simulations indicate that for a given peak intensity, the main pulse has an optimal duration to generate the maximum effective gain. An effective gain as high as 200 cm^-1 was obtained for the optimized drive pulse configuration.
