Paper Abstract

Pulsed laser ablation is at the basis of the processes of laser processing of materials and is used in high-tech production. A feature of laser ablation is the probabilistic nature of ablation destruction processes, which is due to the random spatial distribution of absorbing defects and their characteristics. This results in different laser breakdown threshold values, probabilistic development of laser plasma formation, and a strong relationship between the destruction threshold and the size of the laser radiation interaction region (dimensional effect). The authors carried out studies of laser ablation destruction of polymer materials. The samples were hafnium dioxide films on the silicon surface. The test materials were exposed to a pulse radiation Nd3+:YAG laser to measure the threshold energy density of the laser ablation and to relate the obtained values to the known properties of the nanocomposites.
