Revolution in Fiber Lasers (RIFL)
Abstract
(U) The goal of the Revolution in Fiber Lasers (RIFL) program is to develop multi-kilowatt, single-mode, narrow line fiber laser amplifiers using efficient, high brightness laser diode pump arrays. These narrowline fiber laser amplifiers can then be coherently combined to develop ultra-high power electronically steerable optical phased arrays. In Phase 1 of this program, a 1 kW narrowline, single mode, single polarization fiber laser amplifier will be developed with 15% electrical efficiency and a beam quality of better than 1.4x diffraction limited. In Phase 2 of this program, a 3 kW narrowline, single mode, single polarization fiber laser amplifier will be developed with 30% overall electrical efficiency and better than 1.4x diffraction limited beam quality. Coherent arrays of these high power fiber laser amplifiers will then be developed as part of the DARPA Adaptive Photonic Phase-Locked Elements (APPLE) program (PE 0603739E, Project MT-15) to achieve the requisite power and coherence for future multi-kilowatt high power laser weapons.
