Evaluation of Laser Oscillation Property in Wave Guide Polycrystalline Ceramic

Abstract

The laser characteristics of waveguide sample manufactured by World Laboratory Co., Ltd. were evaluated. Maximum output of 120 W was obtained from approximately 264 W of absorbed power. Greater than 50% slope efficiency was achieved--the target of in this effort--without cracking the sample. However, in the region with 264 W or more absorbed power, saturation of the output power occurred. The saturation of this output is thought to be caused by a thermal cooling factor. To obtain higher output power, introducing a high-power sample cooling system is indispensable. Oscillation experiments of still-higher output are planned for a follow-on series of experiments.
