摘要

In this work we report on a study of the plasma produced in laser ablation of aluminum targets by visible (532 nm) and UV (355 nm) radiation. In particular, we have obtained ion energy distributions through time-of-flight measurements in the laser ablation plasma at different laser fluences (3 - 60 Jcm$+$MIN@2$/). The experimental TOF distributions of ions were fitted quite well by theoretical Maxwell-Boltzmann distributions superimposed onto a common center-of-mass flow velocity. By these fits ion plasma temperature and flow velocity were inferred. We also studied the ion yield at different laser fluences, observing a saturation behavior above a specific incident laser fluence.
