Abstract :
Summary form only given. The Yb:YAG medium was demonstrated to be a promising candidate for high-power 1-/spl mu/m laser systems, as well as for use in a tunable, single-axial-mode microchip configuration. Yb:YAG has a long-storage lifetime (951 /spl mu/s), a very low quantum defect (8.6%), and the 940-nm absorption in Yb:YAG is nearly ten times broader than that of the 808-nm absorption feature in Nd:YAG. Unlike four-level systems, the quasi-three-level structure of Yb:YAG requires strong pumping to overcome the deleterious effects of lower laser level reabsorption.
