Spectroscopic Characterization of Low-Phonon Erbium-Doped BaF2 Single Crystals

Abstract

There is substantial attention on the development of rare-earth doped solid-state laser sources for mid-infrared (mid-IR) applications. Recently, there has been renewed interest in fluorites as laser hosts due to their low phonon energies and compatibility with rare-earth dopants. Barium fluoride (BaF2) is particularly attractive due to its low maximum phonon energy of approximately 330 cm1. In this work, Er3+-doped BaF2 single crystals were grown by a Bridgman technique.
