High Power Fiber Laser with High Beam Quality Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-068 Topic Title: High Power Fiber Laser with High Beam Quality Proposal No.: N121-068-0761 Firm: Agiltron Corporation 15 Presidential Way Woburn, Massachusetts 01801-1040 Contact: Yuanxin Shou Phone: (781) 935-1200 Web Site: http://www.agiltron.com Abstract: Leveraging our extensive production experience in pump combiners and fiber lasers, AGILTRON proposes to fabricate a novel pump combiner which is suitable for a counter-pump scheme. This pump combiner adopts the mode fields between the active fiber used in the amplifier and the passive fiber used for the laser delivery to launch and propagate the single mode only. This PM fiber based count pump combiner is suitable for coherently combine several fiber laser arrays using self-organized passive phase locking mechanisms to generate the high power fiber laser system with high beam quality. In this Phase I Program, we will focus on development of detailed modeling tools for analyzing the performance of fiber combiners for counter-pumping in passive phase-locking systems. A prototype pump combiner will be designed, fabricated and demonstrated in Phase I. A fully functional and improved high power fiber laser system will be developed and demonstrated in the Phase II Program. Benefits: These high power pump combiners have wide military applications such as the high power directional energy weapons, long range rangefinders, high power Lidar and free space communications. The proposed next generation high power fiber lasers have direct application in many commercial markets as well, including industrial welding, drilling, cutting and so on. Fiber laser revenues are set to grow to $300 million by 2012 and are likely to have a significant impact on the penetration of high power lasers into the manufacturing environments on the basis of their superior price / performance (beam quality, efficiency and footprint).
