Abstract
A method of removing material of poor thermal conductivity such as paint, grease, ceramics, and the like from a substrate by ablation without damage to the substrate by delivering to the material to be removed pulses or their equivalent of a laser beam having a wavelength at which the material to be removed is opaque and a fluence sufficient to ablate or decompose the material without damaging or adversely affecting the substrate or its surface.
