Abstract

Nd-doped Y3GaxAl(5-x)O12 (YGAG) materials are investigated for their usefulness as compositionally tuned laser materials. An analysis of line-center wavelength, line broadening, and line strength with Ga concentration is conducted to assess the feasibility of constructing a compositionally tuned 0.94-μm laser. Spectroscopic results on this analysis are presented. A laser rod of Nd:Y3Ga1.35Al3.65O12 was made to lase at 0.94465 μm and its performance characterized. This represents the first such laser demonstration on the 4F3/24I9/2 laser transition in Nd:YGAG. Improved optical quality and the use of compositional variations of the YGAG structure is expected to improve the laser performance as these materials are more fully developed.
