Abstract

Specialty fibers such as chirally-coupled-core fibers show a high potential for further power scaling of single-frequency fiber amplifiers. For the first time, we demonstrate a spliceless all-fiber amplifier, where all optical components are directly integrated in a single Yb-doped 3C<sup></sup>-fiber. Such a spliceless laser design enables a compact and robust architecture using specialty fibers, while maintaining excellent beam properties. At an output power of 336W operating at 1064nm, a fundamental mode content of 90.4% at a polarization extinction ratio above 13dB was measured only limited by the onset of SBS without any impact of transverse mode instabilities or other parasitic effects. This work emphasizes the field of applications of 3C<sup></sup>-fibers in high-power laser systems.
