Spectroscopic Investigations of Materials for Tunable Infrared Lasers.

Abstract

This report describes research on the crystal growth and spectroscopic properties of 4d and 5d transition metal ions in halide and oxide hosts materials. Specific information is given on the fluorescence spectra and lifetimes of divalent Rh, Ru, Pt, and Ir ions in KBr and KCl crystals using time-resolved laser pumping. Differences in spectral properties of charge transfer and d level emission are reported as a function of temperature, annealing and radiation treatments. The spectral properties appear to be suitable for laser materials if higher concentrations of doping can be achieved. (Author)
