在0.07 ~ 0.5 J/cm2的激光辐照范围内，研究了800 nm/40 fs短脉冲激光对Ti的飞秒激光纳米烧蚀。为了确定烧蚀阈值，精确测量了烧蚀速率与激光能量的依赖关系。钛的多次烧蚀阈值为0.074 J/cm2，与前人报道的值吻合较好。为了讨论烧蚀机理，我们绘制了先前公布的所有金属的烧蚀阈值作为功函数和熔化温度的函数。我们发现烧蚀阈值与金属的功函数相关。实验数据表明，飞秒激光烧蚀主要是由多光子吸收和光场电离引起的。
Femtosecond laser nanoablation of Ti by short-pulse laser irradiation 800 nm/40 fs is studied in the laser fluence range of 0.07 J/cm2 to 0.5 J/cm2. To determine the ablation threshold, the ablation rate dependence on laser fluence is precisely measured. Multishot ablation threshold of titanium is found to be 0.074 J/cm2 in which value is good agreement with that reported previously by other group. To discuss the ablation mechanism, all the ablation thresholds for metals previously published are plotted as a function of work function and melting temperature. We found that the ablation thresholds correlated with work function of metals. Experimental data suggested that the femtosecond laser ablation is mainly due to multiphoton absorption and optical field ionization.
