Abstract

Silica fibers are successful at delivering high-power high-energy signals in the near-infrared and visible but suffer from high absorption and color formation in the UV spectrum. Hollow-core negative-curvature antiresonant fibers are promising alternatives as UV radiation has a low overlap with the guiding microstructure. However, their power scaling is hindered by the microstructure power handling and only a few tens to a few hundreds of milliwatt were reported delivered from the nano to the femtosecond regimes. We report on a record single-mode delivery of 23.3W (155μJ) with 89.1% transmission from a 343 nm, 10 ns, 150 kHz laser source developed by Bloom Lasers.
