The polymethylmetacrylate samples were exposed to laser beams of various types of lasers. The modifications of the surfaces of the samples were analyzed by light microscopy and scanning electron microscopy. Numerical approach to thermal distribution for specified power ranges of selected lasers was obtained. The results of polymethylmetacrylate drilling and cutting performed by laser and non-laser means were compared by photoelastic methods.
