Abstract
Laser ablation process of the polycrystalline and foam graphite samples was studied using optoacoustic spectroscopy. High defect density of the foam graphite allows observe extremely high ablation efficiencies and their nonmonotonous dependence on laser fluence with many peaks. It seems photochemical multiphoton evaporation process of the matter in the form of large surface relief fragments takes place besides thermal one.
