摘要

用飞秒激光照射各种适合中红外的玻璃成分（重金属氧化物、氟化物和硫系玻璃），研究其折射率随激光脉冲能量的变化规律。通过等时退火条件研究了它们的热稳定性，确定了它们的擦除温度。测量的指数变化比较从文献收集的值为广泛的玻璃候选者。本文研究的其他硫系玻璃（例如GeSbS和75GeS2-15In2S3-10CsCl）具有非常高的折射率变化（高达5.5·10−2），几乎是重金属氧化物玻璃（2·10−2，康宁9754）或SiO2报道的最大值的3倍，这为中红外光学器件的开发带来了兴趣。然而，由于它们相对较低的热稳定性，它们可以受到限制，因为折射率变化完全消除了它们的玻璃化转变温度（类型）。200-300°C（本文研究的硫系玻璃）。

Overview of laser imprinted refractive index changes and related thermal stability in mid-infrared optical glasses

Various glass compositions adapted to mid-infrared (heavy metal oxide, fluoride and chalcogenide glasses) were irradiated by femtosecond laser and their refractive index variations characterized as a function of laser pulse energy. Their thermal stability was studied through isochronal annealing conditions in order to determine their erasure temperatures. The measured index variations were compared to values collected from literature for a broad range of glass candidates. Additional chalcogenide glasses studied in this article (e.g. GeSbS and 75GeS₂-15In₂S₃–10CsCl) present very high refractive index variations (up to 5.5·10⁻²), almost 3 times the maximum value reported in heavy metal oxide glasses (2·10⁻², Corning 9754) or SiO₂, bringing interest for the development of mid-infrared optical devices. Nevertheless, they can be limited by their relatively low thermal stability, since the refractive index variations fully erase around their glass transition temperatures (typ. 200–300 °C for chalcogenide glasses studied herein).

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
