Abstract
A single-end pumped monolithic fiber laser with 6 kW output has been demonstrated. To obtain a high power output by
means of single-end pumping, a 900 μm double cladding fiber and a corresponding new designed signal/pump combiner are
developed. In experiment, this monolithic fiber laser achieves 6.03 kW output with an M2 beam quality of 2.4, and a center
wavelength of 1079.7 nm. This single-end pumped fiber laser manifests good thermal management ability, and is promising
for higher power scaling..
