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). WebGaussian laser beams have power intensities in the shape of a bell curve (Gaussian). This means that the nominal diameter doesn't include 100% of the laser beam's power. A …
