摘要
运用维格纳(Wigner)分布函数(WDF)研究了高斯-谢尔模型(GSM)描述的部分相干光-光束并合的光束传输特性。推导出了并合光束的光束传输因子(M2因子)、峭度因子(K因子)以及光强分布的解析表达式。研究表明,并合光束的M2因子、K因子、光强分布和束宽依赖于总的空间相干度α,间距xd,束腰宽度w0和GSM子光束数目N,如果子光束具有较大的α值,并合光束在远场更能达到较高的峰值光强和较窄的束宽。
Abstract
The beam combination characteristics of partially coherent beams, which are aligned along one dimension, are studied by use of Wigner distribution function. The formulae of intensity profiles, beam propagation factor (M2) and kurtosis parameter (K) are derived. The analysis shows that the intensity profiles,beam width, beam propagation factor (M2) and kurtosis parameter (K) are dependent on the spatial coherent length, propagation distance, separation and numbers of the beamlets.
