Pulsar Photonics splits the power of a laser beam between more than a hundred processing points

04 Mar. 2014

Laser beam sources are known as ultrashort pulse lasers (UPL) when they send pulses of light with durations in picoseconds or femtoseconds. However, many UPL processes are subject to physically determined performance limitations. By splitting the laser beam into multiple partial beams, however, the power from high performance ultrashort pulse lasers can be fully utilized for microprocessing – which significantly reduces process costs. With its Multi Beam Scanner, Pulsar Photonics of Aachen (Germany) is presenting a commercial solution for multiple beam processing with a galvanometer scanner for the very first time at HANNOVER MESSE 2014.

The principle of the Multi Beam Scanner involves splitting a laser beam into numerous partial beams with a diffractive beam splitter. Using an adapted projection lens, the beam splitter is reproduced in a galvanometer scanner. At the workpiece level, multiple processing points can then be generated that precisely follow and replicate the movements of a scanner. The system is thus perfect for speeding up laser processes for the production of repetitious structures or for parallel processing of the same components. Increased process speeds and the more efficient utilization of the laser system reduces manufacturing costs over the long term.
