Abstract

In this paper, high-power fiber lasers and amplifiers based on multimode interference (MMI) in active large-core multimode optical fibers are proposed and their properties are investigated. Experimental results and simulations indicate that such fiber lasers and amplifiers are promising candidates for high-power miniature solid-state lasers. Utilization of the MMI leads to remarkable spectral and spatial features of fiber lasers and amplifiers such as generation of high-power diffraction-free beams.
