Near- and middle-ultraviolet reconfigurable Raman source using a record-low UV/visible transmission loss inhibited-coupling hollow-core fiber

•Two types of Raman sources emitting in the near and middle ultraviolet.•New record low-loss inhibited-coupling hollow-core fiber (5 dB/km at 480 nm).•Raman comb in a hydrogen-filled HCPCF with lines from 270 nm to the near-infrared.•Dual-wavelength Raman source tuned to the ozone absorption band in the ultraviolet.•Sources exhibit a very small footprint and are solarization-free.
