Growth, Spectroscopy and Lasing of Titanium-Doped Sapphire

Abstract

The announcement of efficient, broadly tunable laser action in titanium-doped sapphire has inspired considerable work. Experiments at NRL, and elsewhere have demonstrated successful lasing using both flashlamp and laser pumping. Crystal quality, however, is in great need of improvement, since loss within the material is as much as an order of magnitude greater than would be expected for high-quality sapphire. In this paper we discuss some of the problems associated with the growth of this material and point out their effect on laser performance. We also show some areas where the spectroscopy of this material is not well understood, and propose some explanations for these spectroscopic features. Keywords: Laser crystals; crystal growth.
