摘　　要：矢量涡旋光束是一种新型的结构光场,具有螺旋相位和横截面各向异性偏振分布,在光镊、旋转体探测、光通信、高分辨率成像、量子信息等领域展现出广泛的应用前景。随着研究的不断深入,对矢量涡旋光束的复杂光场模式分布要求越来越高,给矢量涡旋光束的生成技术带来了巨大的挑战。此外,如何更加实用且有效地完备表征矢量涡旋光束的模场分布、模式特性亦是其应用的重要基础。本研究团队长期从事包括矢量涡旋光束在内的结构光场调控及应用技术研究,提出了多种输出模式连续可调的矢量涡旋光束腔外、腔内生成技术。介绍了近年来本课题组在矢量涡旋光束的表征和腔内生成方面的主要工作,包括矢量涡旋光束总角动量态的四参量表征法、激光谐振腔内横纵模调控技术等,并在此基础上报道了人眼安全波段全固态矢量涡旋光束激光器。Vectorial vortex beams(VVBs)are new type of structured optical fields with helical phase and spatial inhomogeneous polarization.It has already shown broad applications in domains like optical tweezers,rotator detection,optical communication,high-resolution imaging,quantum information and other fields.With the continuous deepening of research,the requirements for more complex optical fields of VVBs are getting higher and higher,which brings huge challenges to the generation technology of VVBs.In addition,how to represent such complex optical fields of VVBs more practically and completely is also an important basis for its application.The author’s team has been engaged in the research on the manipulation and application of structured beams like VVBs,and has proposed a variety of extra-and intra-cavity generation of VVBs with selective output modes.In this paper,recent advances of VVB representation and intra-cavity generation are introduced and reviewed,including the four-parameter representation,the intra-cavity regulation of transverse and longitudinal modes of VVBs,and the eye-safe solid VVB laser as well.
