Photoionization-pumped gain at 185 nm in a laser-ablated indium plasma

Lacy, R. A ; Nilsson, A. C ; Byer, R. L ; Silfvast, W. T ; Wood, O. R and Svanberg, Sune LU (1989) In Journal of the Optical Society of America B: Optical Physics 6(6). p.1209-1216
Abstract
We reportwhat is to our knowledge the first production of gain by inner-shell photoionization of ions. Photoionization of 4d electrons from In$+$ ions created a population inversion on a 185-nm In2$+$ transition. This scheme is an isoelectronic scaling of the 442-nm Cd$+$ laser. A single-pass gain constant of 0.9 {\textpm} 0.3 cm{\textminus}1 over a 0.4-cm path was pumped by soft x rays generated by less than 50 mJ of 1.06-$\mu$m light focused onto a tantalum target. Laser ablation of a liquid-indium target provided a high density (1016 cm{\textminus}3) of ground-state In$+$ ions for this scheme. An indium amplified spontaneous emission laser and a synchronously pumped indium laser oscillator are proposed.
