Spectroscopy and Laser Performance of Ti3+ Doped and Cr3+, ND3+ Co-Doped Crystals

Abstract

Lasers used in airborne applications need to be compact, rugged, versatile, and efficient. The objective of this in house research program was to explore, assess, and demonstrate the performance of new, solid state laser materials which have high efficiency and broadband tunability. The temperature dependent spectroscopy of titanium doped sapphire was investigated in detail. Laser performance of commercially available Ti:sapphire crystals was demonstrated to be near the theoretical quantum slope efficiency limit. Tuning was demonstrated over the 695-864 nm region using a single set of mirrors. Mirror damage limited energy per pulse to 8 mJ. Ti3+ ions were introduced into other crystalline hosts. Spectroscopic samples of Ti:YA103, Ti:YAG, and Ti:GSAG (Gd-Sc-Al garnet) were grown. Absorption, fluorescence and fluorescence lifetime were measured for each of these samples.
