Micromachining with copper bromide laser

In the present paper the possibility of the Copper Bromide (CuBr) laser as an attractive tool in the micromachining of different materials has been demonstrated. High-quality percussion drilling, trepanning, scribing, and precision cutting were demonstrated on metals and ceramics with a negligible heat affected zone (HAZ). These good results were achieved with the combination of high power, short pulses, visible radiation and close to the diffraction-limited beam quality.
