Optical Properties of Chromium and Neodymium in Zirconium-Barium- Lanthanum-Aluminum Fluoride Glass

Abstract

The optical properties are reported of chromium and neodymium doped in zirconium-barium-lanthanum-aluminum fluoride glass (ZBLA). The fluorescence of Cr(3+) and of co-doped Cr(3+), Nd(3+) glasses is investigated. Fluorescence decay rates of Cr(3+) and Nd(3+) are measured at various temperatures, and the excitation transfer efficiency between Cr(3+) and Nd(3+) is determined. The absorption spectrum of Nd(3+):ZBLA is characterized in terms of the Judd-Ofelt model of crystal field-induced electric-dipole transitions. The three phenomenological intensity parameters for Nd(3+) in ZBLA glass Omega sub 2,4,6, are compared to those obtained for Nd(3+) in Y3Al5Ol2, Gd3S2Al3Ol2, and LHG-8 glass.
