摘要
运用Ｃｏｌｌｉｎｓ衍射积分推导了贝塞尔－高斯光束经圆光阑限孔透镜后的轴上光强表达式。通过数值计算讨论了轴上光强的分布规律。对贝塞尔光束经回光阑限孔透镜后的轴上光强分布进行了理论和实验研究。
Analytic expressions for axial intensity distributions of a Bessel-Gauss beam focused by an aperture lens have been derived by using Coffins diffraction integral, and discussed by numerical calculations. As a limting case, the axial intensity distributions of a Bessel beam focused by an aperturelens have also been studied both theoretically and experimentally.
