Abstract: The influence of phase mismatch, group delay, and optical losses of waveguide modes on third-harmonic generation in a hollow fibre is investigated. An analytical solution to the equation governing the slowly varying envelope of the third-harmonic pulse in a leaky mode of a gas-filled hollow fibre is derived. Optimal conditions for third-harmonic generation in such a fibre are determined for different pump pulse durations and various rare gases.
