Development of Ceramics for High-Power Lasers

Abstract

The ceramic laser gain media fabricated during the 2010 calendar year effort have nearly ideal microstructure. Optical characterizations, using 633 nm laser, showed that the scatter loss is almost zero for the newly fabricated ceramic gain media. The high optical quality of the fabricated ceramics showed high resistance to laser damage when exposed to 1064 nm laser radiation. When used in a laser setup, these devices produced 120 W output power with slope efficiency of 53%. The demonstrated slope efficiency is comparable to that obtained using single crystal and ceramic media obtained from Konoshima.
