Trumpf introduces picosecond spectrum TruMicro 2000 laser machine

The Trumpf TruMicro Series 2000 is described as an affordable entry-level machine whose lasers, with a pulse duration of just 20 picoseconds, deliver 10 micro joules of pulse energy and an average output power of 10 W at high brilliance. With an M2 beam quality of less than 1.3, it is suitable for high precision separation and structuring. Accordingly the TruMicro 2000 is able to ablate thin film layers made from polyimides or other plastics just 100 nm thick. The system is also suitable for black marking on anodised aluminium, for high-end ornamentation, typically on smartphones and tablet PCs. The beam generated passes through the anodised layer and causes a change of colour in the metal which has a dark appearance even though the material's surface remains untouched. Each individual picosecond pulse is monitored from generation to delivery via an external modulator. As a result, output power and pulse energy are kept at exact levels regardless of any external influences. A patented Trumpf double feedback loop system controls this process, ensuring the specified power level is delivered to the workpiece. These small lightweight lasers are also distinguished by their compactness and their choice of control options. This allows them to be easily integrated into production lines. Variations operating in the infrared or green wavelengths extend the user's choice in terms of focusing ability and the required absorption properties.
