High-Precision Machining with Copper Bromide Laser

摘要

It has been demonstrated that the Copper Bromide Laser is a promising tool in the micro-machining of several materials (Al, Cu, Brass, Si). These results were achieved with the combination of high average laser power, short pulses, visible radiation, high repetition rate and close to the diffraction-limited beam divergence. The heat-affected zone (HAZ) was relatively small and depends from the cutting speed and number of repetition.
