Paper Abstract

The formation of blind narrow channels in polymethylmethacrylate (PMMA) volume under the action of one pulse of TEA CO2 laser radiation hues been discovered and experimentally studied. An existence of three distinctive regimes of laser-polymer interaction in different power density ranges due to an influence of plasma formation at low threshold nearsurface optical breakdown was shown. The formation of spherical type micro damages in a near surface layer of polymer produced due to local volume boiling were observed.
