High-Efficiency, High-Temperature Laser Diodes for Naval High-Energy Laser Applications Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-013 Topic Title: High-Efficiency, High-Temperature Laser Diodes for Naval High-Energy Laser Applications Proposal No.: N121-013-1255 Firm: Laser Operations, LLC 15632 Roxford St. Sylmar, California 91342-1265 Contact: Jeffrey Ungar Phone: (818) 986-0000 Web Site: http://www.qpclasers.com Abstract: Recent advances in diode laser quantum-well designs have demonstrated significantly increased operating temperatures with good efficiency at wavelengths ranging from 808 to 1500 nm. Similar quantum-well designs will be adapted to 976 nm with the goal of achieving 70% wallplug efficiency at 80 C. Benefits: High efficiency, high operating temperature 976 nm pump for fiber lasers and amplifiers diodes will greatly improve the efficiency, size, weight and cost of high energy laser directed energy weapons. These benefits will also result in lower cost, lighter and more compact fiber lasers for industrial applications such as welding and cutting. Return
