在严格全光纤化的掺铒ZBLAN光纤放大器（EDZFA）中实现了高功率中红外超连续谱（SC）。EDZFA由2.0-3.5 µm光纤SC激光器接种，并在976 nm处泵浦。在500 kHz的脉冲重复频率下，输出SC范围为2.7至4.2 µm，达到创纪录的4.96 W输出功率，整体斜率效率为17.3%。据我们所知，这封信展示了MIR地区第一个全光纤化放大器内SC一代，它具有进一步功率缩放的巨大潜力。
A high power mid-infrared (MIR) supercontinuum (SC) is demonstrated in a strictly all-fiberized Er-doped ZBLAN fiber amplifier (EDZFA). The EDZFA is seeded by a 2.0-3.5 µm fiber-based SC laser and pumped at 976 nm. At pulse repetition rate of 500 kHz, the output SC spanning from 2.7 to 4.2 µm reaches a record output power of 4.96 W with an overall slope efficiency of 17.3%. This Letter, to the best of our knowledge, demonstrates the first all-fiberized in-amplifier SC generation in the MIR region, which has significant potential for further power scaling.
