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.
