摘　　要：定义了适用于多模固体激光器的光束质量参量，理论和实验结果表明，定义的光束参量的变换遵循ＡＢＣＤ 法则，通过成像系统后保持不变。In laser applications,it is a very important pro blem to define the beam quality of the laser beam,especially for the multi mode l laser beam.In general, M 2 factor is a useful parameter relative to di vergence angle and waist diameter of laser beam.If we determined M 2,th e beam quality parameters of the practical beam,defined with second order moment s,would determine.In practice,the precise measurements of these second order moments are difficult.This paser emphasized that beam parameters defined wi th energy distribution of beam profile are satisfied with ABCD law for s table cavity solid laser,because the output beam is the sum of multi orders of G aussian lights.The experiments and analysis are well agreeable.
