| 摘 要： | 高功率全光纤中红外超连续光源在基础科学研究、环境、医疗以及国防安全等领域有着重要应用。目前用于研制上述光源所用的非线性介质为氟化物玻璃光纤。但是氟化物玻璃光纤的损伤阈值低、化学稳性差，这在一定程度上影响了氟化物玻璃光纤在实用化高功率中红外光源研制中的应用。为了进一步提升中红外超连续光源的性能和研制实用化高功率中红外超连续光源，最近制备出了一种具有较好热稳定性和化学稳定性的氟碲酸盐玻璃（TeO2-BaF2-Y2O3，TBY），并利用其作为基质材料，设计制备出了一系列氟碲酸盐玻璃光纤。利用这些光纤作为非线性介质，研制出了光谱范围覆盖1.4~4 m的高相干超连续光源，光谱范围覆盖0.4~5.14 m的宽带超连续光源和平均功率大于10 W、光谱范围覆盖947~3 934 nm的超连续光源。

| Abstract: | High power all-fiber mid-infrared(MIR) supercontinuum(SC) light sources have attracted much attention for their wide applications in fundamental research, environments, medicine, and national defense security. Currently, such SC light sources are mainly based on fluoride glass fibers. While the relative low damage threshold and poor chemical durability of the fluoride glass fibers influenced their applications in practical high power MIR SC light sources. For further improving the performances of the MIR SC light sources and developing practical high power MIR SC light source, a fluorotellurite glass(TeO2-BaF2-Y2O3, TBY) with good thermal and chemical stabilities was developed, and fluorotellurite glass fibers was fabricated based on it. By using the fluorotellurite glass fibers as the nonlinear media, coherent SC generation from 1.4-4 m and broadband SC generation from 0.4-5.14 m were obtained in our experiments. Moreover, SC light source with an average power of 10 W was also obtained, and the spectral range covered 947-3 934 nm. |
