The incubation process in polyimid was investigated at 337.1 nm UV photoablation. The threshold number of incubation pulses needed to start the ablation is proportional to a reciprocal cubic function of the fluence and does not depend on the repetition rate of the laser between 0 and 20 pps. A simple model is presented to explain these characteristics.
