    The M2-Factor of a Coherent Combined Beam

      摘要
    • 摘要: 推导了TEM00、TEM10、TEM01、TEM00和TEM01光束两两相干叠加的M2因子的解析表达式, 并数值对比分析了一些光学参数对叠加场M2因子的影响程度, 得出了诸如光束的束腰宽度对M2因子影响相对较大等结果。最后, 文章开展了实验, 测量了两个TEM00相干叠加的M2因子, 理论结果和实验结果吻合得很好。

       

      Abstract: Analytic expression of the M2-factor of a coherent field combined by two beams, such as TEM00、TEM10 and TEM01, is presented in this paper.And some properties of these M2-factors are obtained by numerical calculation.An experiment is carried to prove these properties of the M2-factor of the coherent field superimposed by two TEM00 beams in the end.
