Abstract

A system is proposed whereby Zn atoms that are photoionized by soft x rays from a laser-produced plasma undergo selective super-Coster–Kronig decay leading to inversion and lasing on several XUV Zn iii transitions. Calculations indicate that lasing will occur when a moderate-sized (∼10-J) 1.06-μm pump laser is used.
