beam propagation factor

基本解释

The beam propagation M2 factor is a useful parameter for characterizing laser beam.
光束傳輸M2 因子是表征激光束的有用蓡量。
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.
利用單色光束傳輸特性的研究方法，我們可以通過新定義的彩色光束M2因子來研究彩色光束的傳輸特性。
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，我們利用光束半逕的二堦距定義，推導了三種不同偏振分佈光束列陣的瑞利距離和光束傳輸因子。
