摘要 由collins衍射积分,推导出了复宗量双曲余弦高斯(EchG)光束通过无光阑透镜后的轴上光强分布公式和轴上最大光强位置满足的一元三次方程,得出了制约焦开关现象的解析条件.在此基础上作了大量的数值分析.结果表明,除了菲涅耳数外,相对入射距离和光束参数都影响焦开关.这些结果将有助于了解EchG光束的聚焦特性. Strarting from the collins diffraction integral,the formula predominating the distribution of axial intensity of elegant cosh-Gaussian beams（EchG）through thin lens without aperture and the third-order equation governing the position of axial maximum intensity is derived and the analytical condition of focal switch of EchG beams is obtained.A large number of numerical calculation results are presented on this basis.It is shown that relative incidence distance and beams parameters influence focal switch besides the Frensel numbers.These results are helpful to understanding the focusing properties of EchG beams.
