摘要

本文通过实验和数值研究了5μm波长左右脉冲在惰性气体填充中空波导中的自压缩特性。我们证明了多mj脉冲在4.9μm处的光谱展宽，以及在孤子脉冲压缩下从85 fs到47 fs的相关脉冲压缩。自压缩产生了在1khz脉冲序列中峰值功率为17gw的亚三周脉冲。建立了数值模型，并与实验结果进行了对比。它允许进一步了解脉冲压缩过程，例如压缩作为气体压力和波导半径的函数的缩放，并预测实际输入参数的亚周期状态下的脉冲压缩。

Self-compression of 5-μm pulses in hollow waveguides

We experimentally and numerically investigate self-compression of pulses around

5 μ m

wavelength in a noble-gas-filled hollow waveguides. We demonstrate spectral broadening of multi-mJ pulses at

4.9 μ m

and associated pulse compression from 85 fs to 47 fs in the solitonic pulse compression regime. The self-compression resulted in sub-three-cycle pulses with 17 GW peak power in the 1-kHz pulse train. A numerical model is established and benchmarked against the experimental results. It allows further insights into the pulse compression process, such as scaling of the compression as a function of gas pressure and waveguide radius, and predicts pulse compression in sub-cycle regime for realistic input parameters.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
