Abstract

Soliton-driven resonant dispersive-wave (RDW) emission is an established route to the generation of frequency tunable ultrafast pulses. In gas-filled anti-resonant guiding hollow-core photonic-crystal fibre (HC-PCF), continuous tuning of RDW generation in both the vacuum (VUV) and deep ultraviolet (DUV) to visible (110 nm to 550 nm) has been achieved [1] and fully characterised to have a temporal duration of a few fs in DUV [2]. Due to the high conversion efficiency (up to 10%), relatively low pump energies are required (few μJ) to get useful UV energy, and so high repetition-rate pump sources can be used [3]. Furthermore, the generated UV emission reproduces the polarization state of the pump pulse. Combined, all of these features make RDW-emission in gasfilled HC-PCF an ideal, and rather unique, source for ultrafast pump-probe spectroscopy in the ultraviolet region.
