和传统的石英光纤相比,硫系元素光纤、亚碲酸盐光纤、氟化物光纤等软玻璃光纤在中红外波段具有较低的传输损耗,以这些软玻璃光纤为非线性介质产生中红外超连续谱的研究均有报道。然而,在高功率中红外超连续谱的实验研究中,ZBLAN(组分为ZrF4-BaF2-LaF3-AlF3-NaF)氟化物光纤表现出了更为优越的性能。2009年,美国密西根大学以 Compared with the traditional quartz optical fiber, the soft optical fiber such as chalcogenide fiber, tellurite optical fiber and fluoride optical fiber has a lower transmission loss in the mid-infrared band, and the medium soft infrared optical fiber produces medium-infrared super-ultra Continuous spectrum studies have been reported. However, ZBLAN (ZrF4-BaF2-LaF3-AlF3-NaF) fluoride optical fibers exhibit superior performance in high-power mid-IR supercontinuum experiments. In 2009, the University of Michigan to
