Picosecond Laser Uses Cold Processing to Add Precision

Trumpf’s TruMicro 2000 is a picosecond laser for applications including metal engraving, cutting thin films, and corrosion-free marking of medical instruments and chrome-plated plastics. It emits short laser pulses ranging from 0.4 to 20 picoseconds and has a peak power of 20 microjoules. This enables the laser to perform cold processing, meaning it performs the task before the material begins to register a thermal process. This is said to reduce the occurrence of undesirable thermal effects such as micro-fissures and residual melt, enabling precise applications including smooth surfaces and deep black markings.

The laser can accomplish microprocessing applications such as structuring, cutting and ablation.  A “Pulse on Demand” feature applies the laser pulse to a desired location with micrometer accuracy, enabling precise work on a variety of materials. The laser also has a double power regulation that enables the operator to precisely set the power from pulse to pulse.
