We report the fabrication and characterization of Kagome hollow-core antiresonant fibers, which combine low attenuation (as measured at similar to 30 cm bend diameter) with a wide operating bandwidth and high modal purity. Record low attenuation values are reported: 12.3 dB/km, 13.9 dB/km, and 9.6 dB/km in three different fibers optimized for operation at 1 mu m, 1.55 mu m, and 2.5 mu m, respectively. These fibers are excellent candidates for ultra-high power delivery at key laser wavelengths including 1.064 mu m and 2.94 mu m, as well as for applications in gas-based sensing and nonlinear optics.
