1, using focus spot；So that the big core diameter laser of multimode can be flat-top Energy distribution, the small core diameter laser of single mode can be
Gaussian Profile；
2, using defocused spot, laser facula can be class Gaussian Profile, either focus spot or defocused spot, all need
The lengthwise position for changing laser beam could change；
3, actively change laser facula Energy distribution using other optical components, adjusting is not flexible, and higher cost.In addition to
Change laser spot size and light spot energy variation is complex not flexible outer, matches when needing using high power laser light
With high-capacity optical fiber laser, and this laser often because the reason of high power bundling device the price that will lead to laser it is non-
Chang Gao.
