Expected Benefits of Spatial Light Modulators in Metal Processing
Spatial light modulators enable dynamic control of the beam profile, allowing for highly precise processing. In the fabrication of fine structures and complex metal components, the SLM-310 delivers a level of precision that is difficult to achieve with traditional methods, ensuring consistent production of high-quality parts.
The SLM-310 allows for instantaneous adjustment of laser irradiation patterns, significantly reducing processing time. Techniques such as using donut- or ring-shaped beams can enhance speed while minimizing unnecessary thermal input, resulting in improved processing efficiency.
The SLM can split a single laser beam into multiple points and apply distinct patterns simultaneously, enabling the processing of several areas at once. This processing capability shortens takt time and greatly boosts overall productivity.
By precisely controlling laser energy distribution, the SLM-310 concentrates heat only where needed. This targeted energy delivery reduces spatter, improves quality, and mitigates the need for post-processing. It also helps preserve the integrity of temperature-sensitive materials.

Application
■Laser Welding Simulation
This simulation demonstrates the effectiveness of laser welding through precise beam profile control. By optimizing the beam intensity distribution, several improvements in welding quality and productivity can be expected, including (1) reduced spatter droplets, (2) fewer bubbles and voids within the weld, (3) minimized weld marks, and (4) increased welding speed.
