Development of Materials for Spectral Hole Burning Applications
Abstract
It was intended to evaluate growth of europium-doped yttrium aluminum oxide (Eu:Y3Al5O12, Eu:YAG) and europium-doped yttrium silicate (Eu:Y2SiO5, Eu:YSO) crystals to characterize these crystals for spectral hole-burning application. After technical discussions at a topical Workshop and agreement of the Technical Monitor, the scope of the program was enlarged to include growth of rare-earth doped mixed-oxide crystals and growth of Eu:YSO was de-emphasized as these crystals-were available for characterization. The experimental effort involved producing YAG, YSO and YAlO3 (YALO) host crystals and the dopants Eu, Tm, Tb and Ce. High optical quality crystals of Eu:YAG, Tm:YAG, Tb:YAG and Ce:YAG were fabricated from 6 cm diameter boules grown using the Heat Exchanger Method (HEM). The samples were characterized for absorption as a function of wavelength at-SRI International, Menlo Park, CA. Previously-grown Ce:Gd3Sc2Al3O12(Ce:GSAG) crystal was characterized also. The available data is insufficient for choosing a crystal for spectral hole burning application. It is necessary to explore other rare-earth doped mixed oxide crystals and carry out more characterization.
