Paper Abstract

Laser ablation of alumina (Al2O3), aluminum nitride (AIN) and silicon nitride (Si3N4) ceramics by 6 ns Nd:YAG laser operating at wavelengths of 1064 nm, 532 nm and 355 nm is studied. For all materials the maximum ablation rate is observed at wavelength 1064 nm, and the smallest one for irradiation at 532 nm in the case of Si3N4 and AIN. The numerical model, based on the heat-transfer equation describes the temperature distribution in the material and the evaporation process. The calculated depths of the drilled holes are in agreement with experiment.
