Extension of 3p→3s Ion Lasers into the Vacuum Ultraviolet Region

Abstract

The feasibility of extending existing near-ultraviolet ion lasers into the vacuum ultraviolet spectral region is analyzed with a simplified three-state model. Single-pass amplification in a laser-produced plasma of reasonable length, pump power, and rise-time requirements is predicted, especially for high electron temperatures. The results are intended to serve as a basis and incentive for detailed numerical modeling and for experiments.
