| 中文摘要 | ultrafast lasers ablation of cr film was investigated by using double-pulse method. experimental results show that there exists a temporal ablation window effect with each of the double pulses adjusted just smaller than the threshold. when the delay between the double pulses is within the order of 400 ps, the ablation of cr film could happen. when the delay between the double pulses is beyond the order of 400 ps, the ablation of cr film would not happen, and the reflectivity from the surface of the cr film shows a sharp rise at the same time. the two-temperature model was developed into the form of double pulses to explain the experimental phenomena. furthermore, microbump structures were formed on the surface of cr film after ablation by ultrafast double pulses. their heights exhibit an obvious drop between 1 and 10 ps double pulses delay, which is involved with the electron-phonon coupling process according to the numerical simulation. these results should be helpful for understanding the dynamic processes during ultrafast lasers ablation of metal films.
