Abstract
We demonstrate the transmission of 1.8 kW 38 GHz linewidth laser at 1080 nm through a 100 m AR-HCF, maintaining 95% efficiency, near-diffraction-limited beam quality, and no measurable stimulated Brillouin scattering response. Our results also highlight a potential path for high-efficiency multi-kW CW Raman lasing.
