叠合高斯光场研究

Study on the Homogeneity of Overlapped Gauss Field

高斯光场对称分割叠合可获得大范围光强均匀的叠合光场。详细计算分析了一维叠合光场的光强均匀性、光能利用率、平均光强等指标与叠合度ｋ之间的曲线关系，并与同等条件的高斯光场进行了比较。结果表明，在ｋ＝０．５４０时，叠合的高斯光场可获得相当良好的均匀分布，同时，光能利用率和平均光强为同等条件的高斯光场的１．

The overlapped Gauss field can get large range homogeneous field. The overlapped 1 D Gauss field is carefully analyzed and compared with general Gauss field in the intensity homogeneity, utilization ratio of luminous energy and average optical intensity. The analysis results show that a well homogeneous overlapped Gauss field intensity is gotten with satisfactory utilization ratio of luminous energy.
