Abstract
The ionic products from ultraviolet laser photoablation of polyimide and polystyrene have been studied as a function of laser fluence and wavelength. The negative ion spectra give a distinctive "fingerprint" of the polymer sample. The fragments are removed from the surface in a supersonic expansion. Ionic fragments have substantially larger velocities than neutral fragments. The ablation is seen to occur via multi-photon processes.
