摘　　要：研究了由圆锥透镜和凸面镜组成的非稳贝塞尔光学谐振腔.利用几何光学原理,讨论了非稳贝塞尔谐振腔中光线传输的ABCD矩阵和腔内光线实现自再现的条件.从波动光学角度出发,利用惠更斯-菲涅尔衍射积分方程导出了谐振腔两镜面处光场的迭代方程,并通过数值模拟得到了凸面镜曲率半径不同时零阶贝塞尔光束在输出镜面上的光强分布.Unstable Bessel optical resonator consisted of an axicon and a convex spherical mirror is studied. The ABCI） matrix and the conditions of the self-reproducibility rays in the unstable Bessel resonator are discussed by the geometrical optics. Based on the wave optics, the optic filed relation between the two mirrors is obtained using Huygens-fresnel integral equation. Numerical integral is applied to describe the optic field amplitude distribution of zeroth-order Bessel beam at the output mirror with different radius of curvature of convex-spherical mirror. The result of the research has theoretically directive significance to realizing unstable Bessel optical resonator.
