摘要

A piecewise hollow-core fiber (HCF) consists of two or more segments of HCFs that are in tandem, which can extend the functions of currently widely-used gas-filled HCF compressors. In this work, we present a model to study the influence of misalignment on the pulse propagation dynamics, which includes incident angle deviation and transverse shift between two consecutive segments. In particular, we focus on soliton dynamics involving dispersive wave (DW) emission in vacuum ultraviolet range and sub-cycle pulse generation. It is found that DW emission is more sensitive to incident angle deviation due to shorter wavelengths, and an empirical estimation of the incident angle tolerance is obtained. The tolerance of transverse shift is up to 20 μm in the case studies, which can be met in practice. This work provides insights into the working of a piecewise HCF system that can help to build and analyze such systems.
