beam width factor

基本解释

In case of electronic scanning the beam width is broader by a factor of two .
电子扫描时，波束宽度展宽一倍。
It is shown that the beam quality factor of nonparaxial truncated flat-topped beams depends on the truncation parameter, the beam order and the initial waist-width to wavelength ratio.
计算结果表明：非傍轴截断平顶光束的质量因子不仅与截断参数、光束阶数有关，而且与初始束腰宽度和波长之比有关；
