We report a supercontinuum spanning well over an octave of measurable bandwidth from about 1 to 3.7 μm in a 2.1 mm long As₂S₃ fiber taper using the in situ tapering method. A sub-100-fs mode-locked thulium-doped fiber laser system with ~300 pJ of pulse energy was used as the pump source. Third-harmonic generation was observed and currently limits the pump pulse energy and achievable spectral bandwidth.
我们报道了一种在 2.1 毫米长的 As₂S₃光纤锥中使用原位拉锥法产生的超连续谱，其带宽超过一个倍频程，从 1 到 3.7 μm 都可测量。泵浦源是一个具有 ~300 pJ 脉冲能量的基于锁模掺铥光纤激光器系统。观察到了三次谐波产生，这目前限制了泵浦脉冲能量和可实现的光谱带宽。
