New video! UV lasers and fiber lasers differ significantly in their wavelengths, leading to distinct material interactions. Fiber lasers, typically emitting in the near-infrared range, are excellent for metals, marking them through heat-induced changes like ablation or annealing. UV lasers, with their much shorter wavelengths, deliver a "cold" engraving process, ideal for materials like plastics, glass, and some metals where minimal heat damage is desired. UV lasers can also create higher contrast marks on certain materials and are often used for delicate or precise applications where fiber lasers might cause excessive heat or melting. Fiber lasers, on the other hand, excel at engraving metals. Watch my new video where I compare the differences by engraving a wide range of different materials. Link in comments!
