✦ Synopsis

We have analyzed the contributions of purely photochemical and photothermal mechanisms to polymer photoablation. The necessity for the synthesis of these concepts has been shown. The model of laser ablation has been developed to include two dominant processes, the photo-induced decay of macromolecules and the thermo-activated desorption of the products of the photodecay. It is shown that this model is in good qualitative agreement with experimental facts such as the existence of the threshold fluence and the explosive character of the ablation.
