Abstract
AlON ceramic is widely used in the fabrication of high-quality infrared optical components, and has broad application prospects in aerospace, transparent armor, and infrared weapon windows. A laser can be applied to the processing of AlON ceramic in order to achieve a more flexible and efficient processing of AlON ceramic. In this paper, laser drilling experiments were carried out on AlON samples to investigate the mechanism of laser processing of AlON ceramic. A two-dimensional simulation model of laser ablation of AlON ceramic was established, and the process of material removal was analyzed. By comparing the experimental results with the theoretical analysis, the effect of defocus distance on the quality of AlON laser processing is analyzed.
