The demand for marking systems to create durable marks has led to a significant growth of lasers in manufacturing. Qswitchednanosecond pulsed solid state or fiber lasers are used for most of the marking applications today. Manufacturerof marking systems have pushed this growth by providing more powerful or more compact systems.We were able to reduce the overall size of the 3D laser marking head to approx. ? cubic foot. This reduction in size waspossible due to improved pump sources providing higher brightness, improved laser designs, improved electronic designand state of the art packaging technology. The size of approx. ? cubic foot is the most compact full 3D marking systemavailable. In addition, our new laser marking system based on a diode pumped solid state laser shows superior performancecompared to laser marking systems based on fiber lasers of the same or even higher average power. We will show markingapplications in terms of black engraving, annealing and high quality bitmap marking.Due to the optimized optical layout of the 3D marking system, it is possible to mark 3D shaped objects using the samelaser parameters even with objects of different heights. We will present results of a 3D annealing application.Additionally, to achieve high productivity, the laser has to be integrated very easily into the production system in terms ofmechanics, optics and software control.
