Abstract
Laser damage of polymer films produced by 30 ps pulses at 1.06 μm exhibits features of either high-temperature degradation (crater, carbonized particles) or thermo-mechanical fracture (cracks, shrinkage). The conditions that dominate the formation of one or the other type of damage are determined by the relationship between absorption and thermal expansion coefficients. The absorbing inclusions as well as the particular properties of the surface layer influence the damage morphology.
