beam propagation factor

基本解释

The beam propagation M2 factor is a useful parameter for characterizing laser beam.
光束传输M2 因子是表征激光束的有用参量。
Using the new definition of factor M2, the propagation of chromatic beams can be analyzed by the beam propagation factor M2 as same as that of monochromatic beams.
利用单色光束传输特性的研究方法，我们可以通过新定义的彩色光束M2因子来研究彩色光束的传输特性。
In the third chapter, using the second-order momentum of beam radius, the Rayleigh range and beam propagation factor of three different polarized beam arrays are derived.
在第三章中，我们利用光束半径的二阶距定义，推导了三种不同偏振分布光束列阵的瑞利距离和光束传输因子。
