Abstract
We report the experimental characterization of the charged species produced in excimer laser ablation of a superconducting intermetallic compound (YNi 2B2C). By using energy-selective time-of-flight mass spectrometry, we have obtained direct measurements of both mass spectra and kinetic energy distri butions of ions. The investigation has been carried out in the laser fluenc e range 1-5 Jcm(-2), which is typical of laser ablation thin film depositio n. High kinetic energies of the charged component (up to 0.4 keV) have been observed even at moderate laser fluences.
