M-shaping

Function:The function of M-type diffraction optical element is to shape the incident laser into M-Shape, and M-shape refers to the uniform sliding laser spot along a certain direction, the integrated energy distribution is uniform, that is, to form a narrow straight line with uniform energy distribution.

Application:This property of M-Shape laser spot makes it particularly suitable for straight line processing of laser materials, such as laser welding, laser cutting, laser slicing, laser ablation, laser melting and strong laser welding applications.
