The experiments revealed that the ablation thresholds in air are less than half those measured in vacuum. Our analysis shows that thishttp://www.sherpa.ac.uk/romeo/issn/2469-9950/ Publisher's version/PDF may be used on author's personal website or employer's website only (Sherpa/Romeo as of 26/10/2016)Ablation of metals with picosecond laser pulses: Evidence of long-lived non-equilibrium conditions at the surface200510.1103/PhysRevB.71.1744052015-12-12
