Isoelectronic scaling of recombination lasers to higher ion stages and shorter wavelengths

Abstract

Laser action in the visible and ultraviolet (at wavelengths as short as 298 nm) in the higher ionization stages of a number of metal vapors has been produced by a population inversion mechanism based on segmented plasma excitation and recombination. Many of the transitions have never been observed in laser action before by any excitation means and a number of the oscillating transitions in silver, cadmium, and indium form isoelectronic sequences.
