Abstract:
Original structural changes of the surface of a coal sample under the action of pulsed mode laser radiation were studied. It was found that original quasiperiodic columnar structures were formed on the sample surface as a result of the laser action of 10(4) s duration with the frequency of 6 Hz and the single pulse energy density of 1.95 J/cm(2). The diameter of single fragments reached 100 mu m with the distance between them attaining 50 mu m. On the top of the fragments, there were spherical shapes composed of silicon compounds with a size reaching 10 mu m. A scheme of the formation of columnar structure was proposed.
