摘要：
In order to investigate the laser ablation mechanism, the velocity distribution and amount of Sr+ produced by ArF excimer laser irradiation of Sr metal have been measured by time-of-flight (TOF) mass spectroscopy. The velocity distribution of Sr+ agrees with the Maxwell-Boltzmann distribution corrected by the center-of-mass velocity. The relationship between the amount of produced ions and laser fluence suggests that Sr+ is produced by a 4-photon process. Based on these experimental results, a simple model for the laser ablation mechanism of Sr metal is proposed.
