Suppressing Nonlinear and Thermal Effects in Fiber Lasers

Abstract

High-power fiber lasers have found many industrial and defense applications. Some of these applications require high average power and good beam quality, which are hard to achieve simultaneously. The power scaling for narrowband fiber amplifiers is currently limited by the stimulated Brillouin scattering (SBS) and the transverse modal instability (TMI). Various techniques have been developed to suppress these nonlinear effects, but they are based on single- or few-mode fibers with large effective mode area.
