正弦类高斯光束通过硬边光阑的衍射损耗

摘要

对新型光束——正弦高斯光束、余弦高斯光束通过硬边光阑时的功率损耗作了详细的计算。比较和分析了计算结果，并对调制参数的影响进行了讨论。%In this paper，the losses of novel sine-Gaussi an andcosine-Gaussian beams propagating through a hard aperture are calculated in detail. The results are analyzed and compared. The effect of modulation para meter α is discussed.
