Optical Spectroscopy of Ti(3+) Doped YA103
Abstract
This project investigated the optical properties of Ti(3+):YA1O(3) and its potential as a laser material. A large single crystal sample grown by Heraeus was provided by R. Simms of the Naval Air Development Center for investigation. Prior Ti(3+);YA1O(3) crystals investigated in this lab had been grown by Litton Airtron, but they showed large amounts of scattering and absorption loss in the fluorescence part of the spectrum. Since Heraeus used a different method for growing Ti(3+):YA1O(3) (growth under a vacuum), we wanted to see if this crystal might be a better material for lasing. Absorbance, fluorescence, annealing, and lifetime measurements were performed. The crystal of Ti(3+):YA1O(3) was grown by Heraeus in West Germany by using the modified Czochralski method under stringent vacuum conditions. It was 0.1 atom percent (at%) Ti by melt and had a beige-orange tint. The crystal dimensions were 1.026 cm by 1.509 cm by 3.05 cm.
