Beam Shapers-Shaping the Beam from DUV to MIR
Laser beam shaping is a potential technique to optimize laser-material processing applications, especially in improving the surface quality and throughput of 3D additive manufacturing (AM), depth control and edge profile control of machining. There has been some commercially available beam shapers to manipulate the spatial profile. For system integrators or end users, it serves as a module to redistribute laser energy in order to improve the beam utilization efficiency, especially in machining applications. However, the beam quality control is mostly done by estimation, due to the absence of the characterization tool and quantification parameter.
