Abstract

The action of pulsed CO₂ laser radiation (pulse energy of 1 J, pulse time of 70 ns) at the surface of silica (crystal quartz and fused quartz ) have been investigated. By means of spectroscopical and microstructural investigations it has been established the appearrance of two kind of structures – periodical micron-sized structures with the period length close to wave length of CO₂ laser irradiation and nanoclusters with size close to 50-100 nanometers.

Key words: silica / CO₂ laser / nanoclusters
