本文从理论上研究了一种利用金属介质涂覆的空芯波导产生孤子超连续谱的新方法。这种波导的低损耗允许使用具有增强的色散控制的较小直径，并且使得能够产生具有前所未有的高光谱峰值功率密度的两倍频程宽光谱，其比具有高相干性的标准PCF大高达五个数量级。超连续谱的高相干性与等离子体密度突然上升所形成的相干种子成分有关。我们还预言在这种波导中可以产生高功率的真空紫外超连续谱。
In this paper we theoretically study a novel approach for soliton-induced supercontinuum generation based on the application of metallic dielectric-coated hollow waveguides. The low loss of such waveguides permits the use of smaller diameters with enhanced dispersion control and enables the generation of two-octave-broad spectra with unprecedentedly high spectral peak power densities up to five orders of magnitude larger than in standard PCFs with high coherence. The predicted high coherence of the supercontinuum is related to the coherent seed components formed by the abruptly rising plasma density. We also predict that high-power supercontinua in the vacuum ultraviolet can be generated in such waveguides.
