Theoretical study of dispersive wave generation in ar-filled hollow-core PCF above the plasma threshold

Shorter UV wavelengths require higher energy pulses, causing the intensity to enter the ionisation regime when pulse propagation will be influenced by the presence of free electrons. The transition from the "traditional" regime where the Kerr effect dominates to the plasma regime where ionisation becomes important (novel in the context of photonic crystal fibres) is studied numerically in this work.
