我们首次展示了中红外超连续谱产生，直接用来自 2 µm 铥光纤放大增益开关激光二极管的皮秒脉冲泵浦。我们在阶跃折射率 ZBLAN 光纤中实现了 750 - 4000 nm 范围内超过两个倍频程的带宽，在 2450 - 3750 nm 的中红外范围内，瓦特级平均功率和光谱平坦度在 1300 nm 范围内小于 1.5 dB。该系统提供高稳定性、功率缩放能力至 10 W 范围，并展示了一条相对便宜、通用且实用的高功率宽带中红外辐射源的有吸引力的途径。
We present the first demonstration of mid-IR supercontinuum generation directly pumped with picosecond pulses from a Thulium fiber-amplified gain-switched laser diode at 2 µm. We achieve more than two octaves of bandwidth from 750 - 4000 nm in step-index ZBLAN fiber with Watt-level average power and spectral flatness of less than 1.5 dB over a 1300 nm range in the mid-IR from 2450 - 3750 nm. The system offers high stability, power-scaling capability to the 10 W regime, and demonstrates an attractive route towards relatively inexpensive, versatile and practical sources of high power broadband mid-IR radiation.
