Effect of spherically aberrated lens on the quality of super-Gaussian beams

  • 摘要: 根据束宽的传输方程,采用双曲线拟合的方法,计算了超高斯光束通过球差透镜后的M2因子。同时还研究有球差的超高斯光束在透镜几何焦面和实际焦面上的桶中功率(PIB)。以M2因子和PIB作为光束质量评价的参数,进行了详细的数值计算来说明球差对超高斯光束光束质量的影响,并与有球差的高斯光束做了比较。得出了一些有实际应用意义的结果。
    Abstract: Based on the beam propagation equation,the hyperbolic-fit mothed is used to calculate the M2 factor of super-Gaussian beams passing through a spherically aberrated lens.The power in the bucket(PIB) at the geometrical and real focal planes of super-Gaussian beams with spherically aberration is also studied.With M2 factor and PIB as the criteria for laser beam quality,detailed numerical calculations are performed to illustrate the effects of the spherically aberrated lens on the beam quality of super-Gaussian beams.The result is useful for some practical application.
