W. Chang, A. Nazarkin, J. C. Travers, J. Nold, P. Hoelzer, N. Y. Joly and P. St.J. Russell, Opt. Express 19, 21018-21027 (2011)

We numerically investigate the effect of ionization on ultrashort high-energy pulses propagating in gas-filled kagomé-lattice hollow-core photonic crystal fibers by solving an established uni-directional field equation. We consider the dynamics of two distinct regimes: ionization induced blue-shift and resonant dispersive wave emission in the deep-UV. We illustrate how the system evolves between these regimes and the changing influence of ionization. Finally, we consider the effect of higher ionization stages.
