摘要

充气空心纤维是一种方便的工具，用于将激光脉冲压缩到几个周期。为相对较低μJ能级的激光脉冲开发紧凑、高效和高质量的压缩方案尤其令人感兴趣。在这项工作中，研究了在填充氙的转轮光纤中基于非线性光谱加宽的时间脉冲压缩，然后是啁啾镜系统。当氙压力被调节为在1.03μm附近提供零群速度色散时，中心波长为1.03微米的250fs脉冲被压缩到13.3fs。输入脉冲和压缩脉冲的能量分别为3.8和2.7μJ。压缩质量因子达到1.8。

Compression of Few-Microjoule Femtosecond Pulses in a Hollow-Core Revolver Fiber

Gas-filled hollow-core fibers are a convenient tool for laser pulse compression down to a few-cycle duration. The development of compact, efficient and high quality compression schemes for laser pulses of relatively low μJ-level energies is of particular interest. In this work, temporal pulse compression based on nonlinear spectral broadening in a xenon-filled revolver fiber followed by a chirped mirror system is investigated. A 250 fs pulse at a central wavelength of 1.03 μm is compressed to 13.3 fs when the xenon pressure was tuned to provide zero group velocity dispersion near 1.03 μm. The energies of input and compressed pulses are 3.8 and 2.7 μJ, respectively. The compression quality factor of 1.8 is achieved.

期刊介绍： Fibers (ISSN 2079-6439) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes and short communications on the materials science and all other empirical and theoretical studies of fibers, providing a forum for integrating fiber research across many disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. The following topics are relevant and within the scope of this journal: -textile fibers -natural fibers and biological microfibrils -metallic fibers -optic fibers -carbon fibers -silicon carbide fibers -fiberglass -mineral fibers -cellulose fibers -polymer fibers -microfibers, nanofibers and nanotubes -new processing methods for fibers -chemistry of fiber materials -physical properties of fibers -exposure to and toxicology of fibers -biokinetics of fibers -the diversity of fiber origins
