DPSS Lasers, Inc. (Santa Clara, Calif., USA) is presenting and demonstrating the Samurai UV laser marking system with additional spot sizes and work areas. DPSS Lasers specializes in manufacturing 355-nm wavelength UV laser markers and low-cost UV lasers with high peak powers and repetition rates that are suitable for marking and engraving materials such as HDPE, ceramic, plastics and metals. By using the 355-nm wavelength, the Samurai provides a small spot size and large depth of focus. UV lasers take advantage of a “cold” marking process that does not require high average power levels and allows damage-free marking on many materials. Applications include product coding, micromachining, marking, sapphire scribing, ITO removal, semiconductor marking and medical packaging. Unlike IR lasers, UV can use photo-ablation or photochemical response rather than thermal-ablation, which can damage many materials.
