摘　　要：高阶贝塞尔-高斯(Bessel-Gauss)光束在一定条件下呈现"无衍射"特性,是一种具有广阔应用前景的空心光束。本文首先对高阶Bessel-Gauss光束的产生方法进行了分析和归类,将其产生方式分为主动式和被动式两大类。其次对获得高阶Bessel-Gauss光束的谐振腔法、几何光学法、光学全息法、计算全息法、非线性光学法等实验方法进行了阐述。最后总结了各种方法产生高阶Bessel-Gauss光束的优缺点。Higherorder Bessel Gauss beams shows ＂diffractionfree＂ characteristics under certain conditions. It is a kind of hollow beam that has broad application prospect. In this paper, we summarize and classify the generation methods. They can be divided into two categoriesactive way and passive way. The present generation methodsResonator method, Geometrical optics method, Optical holographic method, computer generated hologram, Nonlinear optical meth od are described and analyzed. Finally we introduce the advantages and disadvantages of each method.
