摘要
首先证明基模高斯光束具有最小的M~2值,进而讨论了多模激光束、部分相干光束和波前畸变光束的M~2值的特性,以及相互之间的关系。
It has been proved that the TEM_00 beam has the minimum propagation factor M ̄2. The specificities of the propagation factor M ̄2 of the Multi-modes laser beam, partially coherent beam and wave-front distorted beam are discussed and compered.
