Abstract

The development of new solid state laser hosts for high optical quality rare-earth ion doped crystals, glasses, and ceramics presents an active area of current materials research. To facilitate the design of materials with optimized emission properties, detailed structural information at the atomic level is essential, regarding the local bonding environment (siting) of the rare earth ions, their second-nearest coordination sphere, and their extent of local clustering, as well as the distribution over separate micro- or nanophases in composite materials. In this project, we seek a fundamental understanding of the spectroscopic and photophysical properties of such material systems on a structural basis, combining EPR techniques as structural tools. The systems studied are glasses and ceramics based on fluoride, fluorophosphate, fluoroborate, and fluoroaluminate compositions. To this end a comprehensive EPR strategy will be developed and applied for characterizing the local environment of the emitter ions. The structural information obtained by these approaches and its correlation with the optical materials properties will be important for developing new design strategies for high power laser materials.
