FREQUENCY-SELECTIVE SURFACE PROCESSING OF POLYMER MATERIALS BY PULSEDCO LASER-RADIATION

An experimental investigation was made of the interaction of radiation from a frequency-selective pulsed electron-beam-controlled discharge CO laser on polymer materials (nylon and polyethylene terephthalate) w ith intense absorption bands near the wavelength similar to 6 mu m. Th e parameters of the interaction (geometry and method of irradiation of a material; temporal, spectral, and energy characteristics of the las er radiation) corresponding to the appearance of microstructures of di fferent types on the surface of the processed material were determined . An analysis was made of the relationship between the structural chan ges in the materials at the microscopic level and visual macroscopic c hanges in the physical properties of the samples processed by laser ra diation.
