The Laser Ablation of Gold Films at the Electrode Surface of a Quartz Crystal Microbalance

Abstract

We report in this letter the amount of gold removed by ablation with a pulsed laser operating at 532 and 355 nm, by using a quartz crystal microbalance as a mass detector. The results indicate that for the 532 and 355 nm pulsed laser ablation of gold thin films, 10 (exp 13) - 10 (exp 15) atom per pulse are removed over the fluence range of 0.5-50. J/sq cm. The amount of ablated material is found to depend on the fluence at constant wavelength, and on the wavelength at constant fluence. In addition, the mass sensitivity distribution across the quartz crystal microbalance electrode has been characterized by using the laser ablation technique.
