A well-known method for the determination of the threshold fluence for laser-induced damage (LIDT) and ablation with single laser pulses is the measurement of the ablated crater area as a function of incident fluence and extrapolation to zero crater area. In this paper, we introduce a general incubation model for a large class of materials, for example dielectric materials and metals, and we compare it to experimental data. We conclude that multi-pulse LIDT measurements can also be based on crater size measurements similar to 1-on-1 damage tests if the incubation does not involve coupling between spatial and temporal processes.
