Abstract. The application of the copper bromide (CuBr) laser as an attractive tool in the cutting of different materials has been demonstrated. High-quality precision cutting was established on several materials with a negligible heat-affected zone (HAZ). That good performance was a result of the combination of high power visible radiation, short pulses, and close to the diffraction-limited laser beam divergence with high-speed galvo scanner beam steering.
