摘要 基于 4× 4二阶矩矩阵 ,对一般光束的M2 因子和本征像散a作了研究 ,得出复杂像散光束、旋转简单像散光束、准直简单像散光束和无像散光束等一些典型光束的M2 因子和本征像散的解析公式 ,并作了分析。研究表明 ,一般而言 ,扭曲会引起本征像散的增加 ,但却不会影响M2 因子。 Based on the 4×4 second-order moments matrix,the M2 factor and intrinsic astigmatism a of general optical beams a re studied.The analytical expressions for the M2 factor and intrin sic astigmatism a of some typical types of beam,such as the general astigma tic beam,rotationally simple astigmatic beam,aligned simple astigmatic beam an d stigmatic beam,are given and analyzed.It is shown that the twist result is an increase of the intrinsic astigmatism,but doesn’t affect the M2 factor in general.
