Pulsed laser based on two-dimensional material optical fiber integrated device and external control(invited)

脉冲光纤激光器在加工、光通信、生物医学、非线性研究等领域有很大的应用前景,所以得到了广泛的关注。为了得到脉冲激光输出需要使用饱和吸收体,其中二维材料具有独特的光电特性,在光学和光电器件中已经有很多的应用,尤其是二维材料具备良好的饱和吸收,制备工艺简单,易与光纤系统集成,工作波长宽等特点,被广泛地应用于脉冲光纤激光器。文中回顾了二维材料和光纤的集成方式以及相应的脉冲光纤激光器的输出特性,并且对这类脉冲光纤激光器进行了外场调控的研究。

Pulsed fiber lasers have raised extensive attentions for their great application prospects in material processing and fabrication, optical communications, biomedical fields and research of nonlinearity. Saturable absorbers（SA） are used to obtain pulsed laser, two-dimensional materials have unique optical and electrical properties, which have many applications in the fields of optical and optoelectronic devices. In particular, they are widely used in pulsed fiber lasers, due to the features including saturable absorption, simple preparation process, easy integration with optical fiber systems, wide operating wavelength. This article reviews the pulsed fiber laser applications based on the integration of two-dimensional materials and optical fibers, and dicusses the external field controls of such pulsed fiber lasers.
