Research on Visible to Mid-infrared Pulsed Fiber Lasers Modulated by Novel Two Dimensional Materials

新型二维材料如石墨烯、拓扑绝缘体、过渡金属硫化物和黑磷等不仅具有良好的可饱和吸收特性,而且拥有宽带运转、制备简单、成本低廉和兼容性好等优势,是光调制器件的完美选择之一,被广泛应用于脉冲光纤激光器领域,成为激光研究领域的前沿热点之一.以厦门大学光电子技术研究所近几年的相关研究成果为主要对象,结合国内外研究进展,介绍了二维材料的制备/表征、非线性可饱和吸收特性的测量,并重点阐述了基于二维材料的可见光、近红外至中红外宽波段的调Q/锁模光纤激光器的研究动态.

The novel two dimensional （2D） materials including graphene,topological insulators （TIs）,transition metal dichalcogenides （TMDs） and black phosphorous （BPs） not only offer distinct saturable absorption properties,but also possess advantages of broadband operation,low cost and fiber compatibilities.These unique optical properties of 2D materials enable them to be one of the deal choices for developing amplitude modulators and finding enormous applications in pulsed fibfocuses on,but not Hmited tothe research works conducted by the Opto-electronics Technology Institute of Xiamen University in re-cent years.Fabrication,characterization and saturable absorption measurements of the 2D materials are introduced firstly.Then theoverview and progress on visible to mid-infrared broadband fiber lasers, passively Q-switched/mode-locked by 2D materials saturable absorbers, are specially presented.
