Abstract
Transparent YAG ceramics with nearly the same optical characteristics as those of a single crystal were fabricated by a solid-state reaction method using high-purity powders. The average grain size and relative density of the 1.1 at % Nd:YAG ceramics obtained were about 50 micrometers and 99.98% respectively. An oscillation experiment was performed on a cw laser by the diode laser excitation system using the fabricated ceramics. The experimental results indicated an oscillation threshold and a slope efficiency of 309 mW and 28% respectively. These values were equivalent or superior to those of 0.9 at % Nd:YAG single crystal fabricated by the Czochralski (CZ) method.
