A high-power all-fiber supercontinuum (SC) source in a highly germania-doped fiber (GDF) pumped by a picosecond thulium-doped master oscillator power amplifier (MOPA) system is presented. By further optimizing the length of the GDF, the long-wavelength edge of the wideband flat SC can be broadened to 3 μm. The flat SC has an average output power of 11.62 W and a 3 dB bandwidth of 750 nm. The power proportion beyond 2400 nm is as high as 55.3%. To our knowledge, this SC average output power is the highest from a highly GDF.

使用超过 2400 nm 的高功率比例高锗掺杂光纤产生超连续谱

介绍了一种高功率全光纤超连续谱 (SC) 源，该光源位于由皮秒掺铥主振荡器功率放大器 (MOPA) 系统泵浦的高掺锗光纤 (GDF) 中。通过进一步优化 GDF 的长度，宽带平面 SC 的长波长边缘可以加宽到 3 μm。扁平 SC 的平均输出功率为 11.62 W，3 dB 带宽为 750 nm。2400nm以外的功率比例高达55.3%。据我们所知，这个 SC 平均输出功率是高 GDF 中最高的。
