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。
First of all, it is proved that the fundamental mode Gaussian beam has the smallest M ~ 2 value, then the M ~ 2 values of the multimode laser beam, the partially coherent beam and the wavefront aberration beam are discussed, and the relationship between them is also discussed.
