摘要：

Ablation depths of stainless steel targets irradiated by 80-fs laser pulses at a flux F less than or equal to 40 J/cm(2) (intensity less than or equal to 5 X 10(14) W/cm(2)) in the presence of air at atmospheric pressure are experimentally measured. These values are lower than the theoretical predictions for metal targets in vacuum. Results are analyzed on the basis of the role of the ambient gas and of crater formation on the behavior of the ablated material.
