摘要

Based on the linear dependence of laser pulse energy on the ablation area, the ablation threshold fluence of sapphire is calculated in this paper. Meanwhile the threshold fluence of sapphire as a function of pulse duration is studied with an ultra-short pulse laser. The experimental results agree well with the theory of avalanche mode. Finally we discussed the photon absorption mechanism of the conduction band electrons in Al₂O₃.
