Abstract The transitions between the multiplets of 42 P → 42 D and 42 P → 52 P in Ga have been studied by observing the ions produced in the ablation of a GaAs surface using a tunable dye laser. The asymmetric spectral profiles of the 42 P → 42 D transitions, and the large differences in laser power dependence of the ion yields for the different resonant schemes were observed and analysed. The experimental data are interpreted as resulting from laser-induced collisional processes, especially, from optical collisional excitation and energy-pooling ionisation.
