Higher-contrast, more homogeneous laser markings on plastics
For some plastics, the MOPA laser can display its strengths - short pulses and thereby less material heating. The MOPA laser can laser-mark plastics which are difficult to mark with a conventional fiber laser, in a clearly higher-contrast and more homogeneous manner. Thereby, the material burns less and foams less (e.g., ABS). Especially on dark plastics (e.g. PA 66 GF, PA 6 GF, PP GF, etc.), the shorter pulses often produce “nicer”, lighter markings, which results in a higher contrast. This results in a better contrast, offering you a good (machine) readability.
