摘要
对由两束相对传输的偏心高斯光束相干叠加而成的光束的传输特性进行了研究 .结果表明 ,这种光束的传输因子 M2 不是常数 ,而是随传输距离振荡的 .为了消除振荡 ,引入了平均光束传输因子 M2
It was studied in the paper the propagation characteristics of beams formed by superposition of two decentered Gaussian beams. The results showed that, the propagation factor M\+2 was changing with propagation distance. [WT5,5”BZ]For practical usage,it was introduced also the average propagation factor \{M\+2\} .
