In all fiber optics, loss in the visible and UV is restricted by scattering. By improving the core roughness of hollow-core fibers, record attenuation values at short-wavelengths were achieved, opening exciting prospects in visible and UV-photonics.

International audience; We report on the development of new state-of-the-art ultralow-loss hollow-core fibers guiding in the short-wavelength range. The new record low attenuation values are as low as 50.0 dB/km at 290 nm, 9.7 dB/km at 369 nm, 5.0 dB
