通过从光参量放大器泵浦11 cm长的阶跃折射率硫化物光纤，获得了∼330fs脉冲，功率为4.0μm，在相对较低的功率阈值(∼3000W)下，在±15d B的动态范围内，获得了跨度为1.8~∼10μm的中红外超连续谱。
By pumping an 11-cm-long step-index chalcogenide fiber with ∼330 fs pulses at 4.0 μm from an optical parametric amplifier, mid-infrared supercontinuum generation spanning from ∼1.8 to ∼10 μm within a dynamic range of ±15 dB has been demonstrated at a relatively low power threshold of ∼3000 W.
