摘　　要：贝塞尔光束以其独特的无衍射传输特性得到了广泛的关注,在光学操控、光学加工、信息传输、光学成像等领域具有巨大的应用前景。为了丰富光束的传输特性,通过不同手段对贝塞尔光束传输的调控成为了热点问题。研究者提出不同的理论和方法,通过对贝塞尔光束进行不同维度的调控,构造了沿任意轨迹传输、轴上强度和偏振可调的新型类贝塞尔光束。从贝塞尔光束的基本特性出发,总结了近年来贝塞尔光束传输调控相关的研究进展,包括贝塞尔光束的传输轨迹控制、轴向强度和偏振态控制、束宽控制等基本调控手段,并分析了其传输和调控机理。Significance The invention of lasers has led to a boom of laser technology in various science and engineering of many interdisciplinary fields,which have been widely applied in optical manipulation,precision measurement,optical communication,laser processing,microscopy imaging,and so on.However,the simple propagation characteristics of the traditional Gaussian laser mode have hit the bottleneck in the further development of laser technology and failed to meet the ever-increasing needs in the related fields.Consequently,light field manipulation has emerged.By modulating the amplitude,phase,and polarization of the light field,many new types of spatially structured fields with novel physics effects or propagation properties have been proposed.Optical vortices and cylindrical vector beams are among the most well-known examples.To resist beam diffraction and environment disturbance,researchers have discovered a new class of spatially-structured field named“non-diffracting beam”.Theoretically,a non-diffracting beam can maintain its transverse intensity profile during propagation and can propagate over long distances with little beam spreading.Subsequently,a series of non-diffracting beams with different spatial structures,such as Mathieu beams,Weber beams,Airy beams,and Bessel beams,have been proposed,all of which exhibit the common characteristics of non-diffracting beams.As a typical non-diffracting beam,the Bessel beam quickly attracts great attention of research after being proposed as a propagation-invariant solution of the Helmholtz equation.Extensive research has been conducted on non-diffracting beams,including the applications in improving microscopy imaging quality and the performance of optical trapping.With the continuous development of light field manipulation,researchers have gradually attempted to control Bessel beams through different means by modulating or superposing the Bessel beams.Modulated Bessel beams can behave the self-accelerating propagation with nonlinear trajectories,with tunable on-axi
