X-ray lasing in a Na/Ne plasma environment

Abstract

An investigation has been conducted to determine the feasibility of generating conditions favorable to population inversion, gain, and x-ray lasing in a two-component plasma consisting of sodium and neon. An intense laser beam is assumed incident on both sides of a Na/Ne slab target separated by a carbon thermal buffer. Temperature and density profiles of the laser target interaction are calculated using a Lagrangian hydrodynamics model. Level populations and radiative emissions are evaluated using a collisional-radiative equilibrium model including opacity effects. It appears possible to achieve measurable gain at 82, 58 and 230 Å from the 3-2, 4-2, and 4-3 transitions of heliumlike neon, respectively. Additionally, by pulse tailoring and target design, it should be possible to enhance the Na pumping power. off
