Abstract

We evaluated the optical properties required for the design of a solar-pumped laser for Nd 3 + -doped ZrF 4 - BaF 2 - LaF 3 - AlF 3 - NaF (ZBLAN) glass. The quantum efficiency (QE) of near-infrared emission from the F 3 / 2 4 state of Nd 3 + using sunlight as an excitation source was 70%. The product of the stimulated emission cross section and the radiative lifetime ( σ se τ r ) of the F 3 / 2 4 I 11 / 2 4 was 1.5 × 10 23 cm 2 · s . The integrated absorption strength in the 450 900 nm region was the largest among Nd 3 + -doped fluoride glasses. The high QE, large σ se τ r product, and large integrated absorption strength indicate that Nd 3 + -doped ZBLAN is one of the most promising materials for solar-pumped lasers.
