Abstract
The influence of higher order waveguide modes on the process of coherent four-wave-mixing (FWM) in a gas-filled hollow fiber is studied for fibers with different inner diameters and different gas pressures. Higher order waveguide modes play an especially important role in FWM within the ranges of gas pressures where FWM processes involving such modes are phase matched due to the compensation of the gas dispersion by the dispersion of waveguide modes.
