SiO$_2$ barrier layer influence on the glass composites with oxide nano films laser ablation destruction

This study concerns the composites optical characteristics dependence on the chemical composition of the oxide nanofilms from TiO$_{2}$-Me$_{x}$O$_{y}$ and on the existence of a SiO$_{2}$ barrier layer. The laser ablation destruction threshold energy density values decrease with the light transmission growth in the visible range of the composites for one- and double-layer nanofilms. These properties measurement results dependences for the composites with one- and double-layer nanofilms can be connected with various structure and composition of the complexes which were formed in the films.
