Abstract
A method and device for photoablation is disclosed wherein photoablation occurs along the interface between a material having a lower energy ablation threshold and a material having a higher energy ablation threshold. The method and device utilize a laser beam having a beam energy density which is less than the higher energy ablation threshold and greater than or equal to the lower energy ablation threshold. By directing such a laser beam to the interface, the material having the lower energy threshold is photoablated while the material having the higher energy threshold is largely unaffected.
