- Аннотация: Laser methods are actively employed in the analysis and restoration of paintings. In several studies laser ablation of real paint layers was carried out, for example, during UV laser ablation surface-enhanced Raman microspectroscopy (LA-SERS) or laser-induced breakdown spectroscopy (LIBS), etc. Although the accuracy of the methods is relatively high the probe (ablated part of the object) disappears in the course of measurements and cannot be further be study with the aid of alternative techniques. In contrast, an experimental technique of the laser ablation for the sampling from the paper was proposed before. Extending the application of the technique to paintings can be useful as an alternative to traditional mechanical sampling methods. The advantage of the laser ablation method lies in the relatively small size of the samples obtained and the damaged area of the sample. Optimal parameters of radiation results to the craters be invisible to the human eye.The aim of the study was to verify sampling by laser ablation on model system (paint layer on primed linen canvas) that is close to a real painting, and to study the physical parameters of the microprobes (ablated part of the object). Six oil paints prepared as a mixture of linseed oil binder and color pigment were used as a paint layers. The size of each paint fragment was 2x2 cm2. The thickness of the paint layer ranged from 0.1 to 0.4 mm.
