Abstract

We present the use of a linearly down-tapered gas-filled hollow-core photonic crystal fiber in a single stage, pumped with pulses from a compact infrared (IR) laser source, to generate a supercontinuum (SC) carrying significant spectral power in the deep ultraviolet (UV) [200–300 nm]. The generated SC extends from the near IR down to ${\sim}{213}\;{\rm nm}$ with 0.58 mW/nm and down to ${\sim}{220}\;{\rm nm}$ with 0.83 mW/nm in the deep UV.
