WebM² or the beam propagation factor ¶. M² is defined as the ratio of the beam parameter product (BPP) for a real beam to that for a perfect Gaussian (TEM:math: _ {00}) beam. … Web7 apr. 2024 · (1) The minimum beam diameter Z = 0 can be obtained at the material surface. At this point, the maximum energy density can be obtained on the processed material surface, and the melting range is relatively narrow, which determines the processing characteristics. (2) The focus position is on the “+” side (Z > 0).
