| Abstract: | The calculation and measurement of laser beam M2-factor was discussed, then two new methods was proposed. One of them is to obtain M2-factor from the spot size of many cross sections; the other is from the intensity profile of one section. |
| |
| Keywords: | M~2-factor spot size intensity profile beam quality |
