Holo/Or Can Adjust a DOE to Provide Different Intensity Distributions
Laser welding is used in a wide range of industrial applications including automotive, aerospace, semiconductors, electronics, medical, power and defense. The raw laser beam is not the optimal shape for many industrial applications in general and especially in the field of welding, brazing, soldering, and other similar processes. Compared to other laser material processing applications, these processes stand out in terms of the required laser power (multi kW) and the highly multimode beams often used. A process-specific tailored laser intensity distribution can improve throughput, seam height, strength, and the edge smoothness of the joints.
While DOEs provide superior shaping performance compared to variable solutions, they lack shaping flexibility. To deal with this issue, Holo/Or has developed an innovative sub-aperture concept, where the same DOE can provide different intensity distributions by adjusting the DOE relative to the beam.
