Abstract

In this work we present a theoretical estimation for VUV superluminescent laser gain employing electron-impact excitation and Super-Koster-Cronig decay in Zn vapors. The stimulated emission is produced on the 3d⁸4s² ¹G₄ - 3d⁹4p ³D₃ 130.6 nm two-electron transition of ZnIII. We use the existing information on atomic constants available in the literature to estimate the current densities that will be necessary to observe a significant gain, comparable to that observed in an experiment using x-ray excitation, produced in laser induced plasma. Our estimations show that such values of the gain are obtainable by pulsed electron excitation with time longitude greater than 1 microsecond(s) and high but possible current densities of the order of 10 kA/cm².
