Simulation study of a Ne-like Ti x-ray laser at 32.6 nm driven by femtosecond laser pulses

A femtosecond laser driven collisional Ne-like Ti x-ray laser at 32.6 nm is numerically investigated using a hydrodynamic code coupled with an atomic data package for a 100-mum-thick Ti planar target irradiated by a single or double prepulse followed by an intense femtosecond laser pulse. By using an optimized drive pulse configuration, a gain of 40 cm(-1) can be generated from a 5 mmx50 mum line focus using only about 1 J pump energy.
