Abstract

Recent developments of anti-resonant hollow core fibers (AR-HCF) have provided unique opportunities in many areas of fiber optics. In particular, the delivery of high-power single-mode laser beams through AR-HCFs has undergone substantial advancements. These developments have been driven by the potential application of this technology in key areas such as telecommunications, directed energy, and power-beaming over fiber to mention a few. In general, the goal of a high-power laser beam delivery fiber is to preserve the characteristic features of the source to be used at a remote point of interest without suffering deleterious nonlinear effects.

Here, we show the delivery of mid-IR laser light at 4.6 microns and of high-power 1 micron continuous laser light with narrow linewidth.  We demonstrate the transmission of over 2 kW of power through 100 m AR-HCF, maintaining 95% efficiency and near-diffraction-limited beam quality. For linewidth from 38 GHz to 86 GHz a total suppression of stimulated Brillouin scattering is observed.
