摘要	Interactions between ultrafast lasers and metal targets are crucial in various laser micro/nano-machinings. However, the underlying incubation and absorption-enhancement mechanisms remain elusive, which hinders the quality control of laser processing. Herein, we studied the incubation effect and absorption enhancement during multi-shot femtosecond-laser ablations via combining experiments and hydrodynamic simulations, taking aluminum alloy and stainless steels as paradigm materials. Accumulation effects of heat and damage-induced deformation were revealed by the evolutions of microstructures induced by low-energy femtosecond lasers. The calculated ablation thresholds were reduced with shot number, demonstrating the incubation effect. Calculation of threshold fluence via crater diameter is better than ablation depth, because that the latter is determined by different parameters at low- and high-energy conditions. Experimental observations and hydrodynamic simulations indicated that the enhanced absorption could be attributed to several factors, including laser-induced surface micro/sub-micro structures, photoionization, and plasma evolutions.
