A watt-level mid-infrared supercontinuum (MIR-SC) spanning 2.7 to 4.25 μm is generated in an erbium-doped ZrF-BaF-LaF-AlF-NaF (ZBLAN) fiber amplifier (EDZFA). A broadband fiber-based SC covering 2.2-3.1 μm region is used to seed the amplifier. The generated SC has a maximum output power of 1.75 W with an overall slope efficiency of 20.5%. A normalized root mean square (RMS) in power of 0.5% shows that our system is highly stable. This research, to the best of the authors' knowledge, demonstrates both the record power and the record slope efficiency of in-amplifier MIR-SC generation to date.
在掺铒氟化锆钡镧铝钠（ZBLAN）光纤放大器（EDZFA）中产生了一个瓦级中红外超连续谱（MIR-SC），其覆盖范围为 2.7 至 4.25μm。一个覆盖 2.2-3.1μm 区域的宽带光纤 SC 用于种子放大器。所产生的 SC 的最大输出功率为 1.75W，总斜率效率为 20.5%。归一化均方根（RMS）功率为 0.5%，表明我们的系统非常稳定。据作者所知，这项研究展示了迄今为止在放大器中产生的 MIR-SC 的最高功率和最高斜率效率。
