Paper Abstract

Experimental results based on rare-earth-doped fibers have impressively shown that fiber lasers and amplifiers are an attractive and power scalable solid-state laser concept. Based on ytterbium-doped large-mode-area (LMA) double-clad fibers in the continuous regime output powers approaching the kW-range with diffraction limited beam quality have been shown. Average output powers in the order of 100 W even for nanosecond fiber amplifiers have been demonstrated in the pulsed regime. Further power scaling is limited by nonlinear effects, thermo -optical problems or amplified spontaneous emission. In our contribution we discuss power scaling of fiber lasers and amplifiers in the multi kW-range with excellent beam quality based on rare-earth-doped fibers.
