Abstract

The electron paramagnetic resonance (EPR) technique has been used to monitor a variety of titanium-associated centers in doped aluminum oxide crystals. Because of rapid spin-lattice-relaxation times, these EPR spectra could only be observed in the 5 to 25 K temperature range. Among the distinguishable defects are isolated Ti3+ ions, several S=1/2 centers involving Ti3+ ions with adjacent imperfections, and an S=1 center which is either a pair of Ti3+ ions or is a Ti2+ ion. Once specific defect models have been assigned to each of the spectra, the EPR method promises to be a sensitive indicator of Ti-sapphire crystal quality and may be used to help select material appropriate for laser use.
