Abstract
We detect, through time-resolved ion mass spectrometry, the production of carbon oxide ions in the laser ablation of graphite in the presenc e of CO2. The dependence of the ion production on the laser ablation p arameters is investigated and the expansion dynamics of the ablated sp ecies is studied through time and space resolved measurements of the i on yield. We discuss our observations on the basis of reactions involv ing neutral and ionized carbon-based species.
