Abstract. In this work, a phenomenological laser ablation model is developed to predict the ablation morphology of fused silica irradiated by femtosecond single and multiple pulses. It couples the changes in the surface morphology of fused silica and the impact of the incubation effect on the subsequent laser pulse processing.
