UV Laser Marking Machine: Working Principles​

​​355nm UV Laser Marking Machine 3W-25W for Various Plastic Marking​​ 1

 

The UV laser marking machine operates on ​​photochemical interactions​​:

 

  1. ​​Laser Generation​​: A 355nm UV laser emits short-wavelength beams (photon energy: ~3.5eV), focused into micrometer-scale spots (10–15μm diameter) via optical systems.
  2. ​​Material Interaction​​: High-energy UV light ​​directly breaks molecular bonds​​ (vs. thermal ablation), vaporizing surface molecules to create permanent marks.
  3. ​​Cold Processing Advantage​​: Unlike traditional lasers (thermal effects), UV lasers generate ​​≤5μm heat-affected zones​​, avoiding material deformation or discoloration.
