High Power Fiber Laser with High Beam Quality

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.
