Abstract
In laser-induced direct writing of W stripes from an admixture of WCl6 and H2 non-coherent periodic structures have been observed. These structures appear only in the presence of small amounts of O2. Together with this structure formation, an oscillating change in the surface absorptivity and morphology has been observed. A special setup that permits to determine the absorptivity of deposits on a micrometer scale has been developed.
