THE MECHANISM OF CRATER FORMATION AND CHANGE OF POLYMETHYLMETHACRYLATESTRUCTURE IN CASE OF THE ACTION OF LASER RADIATION
It is shown in this work that in case of pulsed laserirradiation in a target the axisymmetric areas having identical values of density and temperature are formed of polymethylmethacrylate. Values of temperature in various areas of the target were estimated theoretically on values of Gryunaezer's function and extent of compressions. It is revealed also that the absorption of laser radiation by the target material with a thickness of 1 mollimeter in polymethylmethacrylate changes the structural morphology, which are fixed on the x-ray diffractogramme.
