Abstract

It is well known that application of stimulated light may influence phase modifications and changes of carbon structure. These effects of laser irradiation, in different working regimes and atmospheres, are widely investigated for fullerenes and diamond structure, but for many other carbon materials, are not. In the presented experiments, we treated by Q-switch ruby and Nd³⁺ YAG laser beams different carbon clothes, produced by pyrolysis (T <EQ 1000 degree(s)C) of cellulose materials in inert atmosphere. The materials are interesting for many applications, including medical. The laser pulse energy was of order of 0.1 - 1 J, in one, or multi-pulse regime. Focused and unfocused beams were used to induce damages and oxidation of sample surfaces. the damages were analyzed by scanning electron microscopy and specific area is measured by Brunauer, Emmet and Teller method, before and after the interaction. Materials exhibited differences in the damaging level and the fiber breaking thresholds. Mechanisms of laser interaction leading to oxidation of carbon type materials are discussed, and the necessary experimental conditions for intended changes are analyzed.
