The article presents the method used to obtain titanium oxide (TiO2) coatings. The presented method combines the production technique by means of a sol-gel method and a laser processing method. The process can be divided into three stages. At the first stage, based on the popular sol-gel method, an appropriate colloid solution (sol) is prepared. At the second stage, the obtained solution is deposited on a substrate and heated in increased temperature. The layers obtained in this way are modified at the third stage by means of laser radiation with wavelength of 532 nm, operating in continuous mode. The laser influence on the heated coatings is a substitute of the traditionally-used calcination. Consequently, the anatase-rutile coatings are obtained.
