摘要
本文从激光材料加工的角度讨论了以Ｍ￣２参数作为光束质量评价标准的可能性。指出对穿透式的加工方式，Ｍ￣２参数可以表示光束的实用价值，但对表面加工方式，Ｍ￣２参数的大小并不能反映光束实际的实用价值。
In this paper,from the point of material processing,we have discussed the possibility of using M￣2 factor to evaluate laser beam quality,It has been pointed out that M￣2 factor is suitable for eval- uation of beam quality in the so-called penetrating processing(i. e. weldding,cuting.drilling,etc.),but it’s not suitable in the so-called surface processing(i. e. surface heat treatment.marking,etc.)
