Abstract

Highly ytterbium-, aluminum- and phosphorus-co-doped silica fibers with low optical losses were fabricated by the MCVD method, utilizing an all-gas-phase deposition technique. Optical and laser properties of the active fibers with a phosphosilicate and aluminophosphosilicate glass cores doped with 1.85 mol% and 1.27 mol% Yb2O3 were thoroughly investigated. With the help of hydrogen loading, it was possible to induce highly reflective Bragg grating in both fiber samples using the standard phase-mask technique and 193 nm-UV laser irradiation. The ultra-short (less than 2 cm long) Fabry–Perot laser cavities were fabricated by inscribing two fiber Bragg gratings (highly and partially reflective FBGs) directly in the core of the fiber samples. The highest pump-to-signal conversion efficiency of 47% was demonstrated in such laser configuration using phosphosilicate fiber. The reasons for the low efficiency of aluminophosphosilicate fiber are discussed.

镱超短腔光纤激光器核心化合物的优化

采用全气相沉积技术，采用MCVD方法制备了具有低光学损耗的高镱、铝和磷共掺杂二氧化硅纤维。深入研究了掺有1.85mol%和1.27mol%Yb2O3的磷硅酸盐和铝磷硅酸盐玻璃芯的活性纤维的光学和激光性能。在氢负载的帮助下，使用标准相位掩模技术和193nm紫外激光照射，可以在两种纤维样品中诱导高反射布拉格光栅。超短（小于2厘米长）法布里-珀罗激光腔是通过将两个光纤布拉格光栅（高反射和部分反射FBG）直接刻在光纤样品的核心来制造的。在使用磷硅酸盐纤维的这种激光器配置中，证明了47%的最高泵浦-信号转换效率。讨论了铝磷硅酸盐纤维效率低的原因。

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
