Abstract:

Transparent ceramic gain-media can lead, when properly engineered, to significant improvements in solid-state laser performance. Amongst the anticipated benefits of such material-based lasers are high-average power outputs with higher efficiencies, improved pulse-energy storage and outputs, higher ultrafast-laser performance, and phased-array operation of guided-wave laser systems. In this research program we focus on the application, design and testing of engineered laser ceramics. We are working on 1 the characterization of the lasing performance of composite laser ceramics, 2 strategies for evolving composites to achieve high laser efficiency and 3 the design of novel ceramic composites to reduce parasitic losses during operation. We hope that the dual focus on correlating processing, performance and optical losses will lead to exceptional quality ceramics and a fundamental understanding about these materials at all levels of manufacturing and use. Dr. A. Ikesue of JFCC is our major international partner, with funding derived through AFOSRAOARD. The synergy between Stanford and JFCC is accelerating progress in the implementation of these materials in high-power laser applications.
