Abstract

The models of UV-laser ablation of polymers can be subdivided into two groups. The first ones assume direct photon-assisted bond breaking. In this case the fluence and the absorption coefficient of the polymer directly determine ablation threshold and rate. This yields simple expressions for the ablated depth vs. fluence, which can be corrected for the screening of incoming radiation, changes in the absorption coefficient, etc.
