Abstract
Gas-filled hollow-core photonic crystal fibres enable nonlinear fibre optics in parameter regimes hitherto impossible with glass-core fibres, such as: ultra-violet transmission, pressure tuneable zero dispersion wavelengths down to 200 nm, and ultra-short duration soliton energies at the microjoule level. Two techniques for ultra-violet light generation in such fibres have utilised these properties: third harmonic generation [1], and dispersive wave generation [2]. In this work we study the phase-matching and gain landscapes of the latter case.
