Abstract

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.

摘要

我们通过求解一个已确立的单向场方程，对电离对在充气的 Kagomé 晶格空心光子晶体光纤中传播的超短高能脉冲的影响进行了数值研究。我们考虑了两种不同的机制：电离诱导的蓝移和深紫外区域的共振色散波发射。我们说明了系统如何在这些机制之间演变以及电离影响的变化。最后，我们考虑了更高电离阶段的影响。
