摘要

摘要:时空锁模为光纤脉冲能量缩放和非线性光学研究提供了巨大的机遇。到目前为止，时空锁模只在正色散耗散孤子和类似的光纤激光器中实现。本文首次在异常色散的中红外氟化物光纤中实验实现了时空锁模孤子激光器。锁模氟化物光纤振荡器在2.8 μm波长处直接产生了创纪录的脉冲能量16.1 nJ和峰值功率74.6 kW。这项工作将时空锁模扩展到孤子光纤激光器，应该引起激光界的广泛关注。

Spatiotemporally mode-locked soliton fiber laser at 2.8 μm

Abstract Spatiotemporal mode-locking creates great opportunity for pulse energy scaling and nonlinear optics research in fiber. Until now, spatiotemporal mode-locking has only been realized in normal-dispersion dissipative soliton and similariton fiber lasers. In this paper, we demonstrated the first experimental realization of a spatiotemporally mode-locked soliton laser in mid-infrared fluoride fiber with anomalous dispersion. The mode-locked fluoride fiber oscillator directly generated a record pulse energy of 16.1 nJ and peak power of 74.6 kW at 2.8 μm wavelength. This work extends the spatiotemporal mode-locking to soliton fiber lasers and should have a wide interest for the laser community.
