Laser marking is widely employed on large scale for part identification and traceability. Lasers mark a wide range of materials that include metals, nonmetals, ceramics, plastics, organics, and semiconductors, to name a few. Laser marking is fast and flexible process that can mark alphanumeric, graphics, logos, barcodes and even bitmaps. Anneal marking, engraving, soft marking are some techniques used to achieve desired marking results.
The good absorption properties of most materials at near IR wavelengths make fiber lasers very attractive for laser marking applications. The beam quality, compact design and maintenance free operation are of particular interest. The CW and Q-switched lasers covers a wide range of applications and fit most marking requirements.
The CW single mode fiber lasers accommodate most marking requirements in metals. The CW output is of extreme importance when fast, clean and shallow non-intrusive markings are required. Examples include removal of thin films on glass, anneal marking on steels, IC marking and coated metals.
Q-Switched fiber lasers on the other hand, with pulse energy up to 2mJ, and 200W average powers provide the high peak powers and nanosecond pulses that can be used to mark shallow to deep engraving in most materials. The high peak power enables to mark even the most reflective materials such as gold and aluminum. Examples include deep permanent markings on heavy-duty gears, auto parts, plastic ear tags, ceramic filters and PC board and marking keyboards.
