Abstract

This paper discusses the surface-relief profiles of quartz glass after it is acted on by the moving focused beam of a cw CO2 laser. The results are explained well in terms of a thermocapillary mechanism of relief formation, if the temperature coefficient of surface tension of the glass changes sign as the temperature increases. The phenomenon whereby a flat floor is formed in the microchannel that remains after the glass solidifies is detected and qualitatively explained.
