Abstract

Electrochromic WO₃ films were begun to find a wide application for new devices of integrated optics such as displays, adaptive mirrors, elements with controlled transparency, etc. Laser technology would be a perspective method for patterning of those films and their local structure modification, so the laser radiation action on WO₃ films begins to attract the attention of various investigators. In the paper some properties of these films and regimes of laser firing are stated. The alterations in coloring effect in the case of furnace and laser firing are founded. For the purpose of laser action optimization it is necessary to measure an actual temperature kinetics in the laser treatment zone and to investigate the structural alterations in WO₃ films in such cases. It is a sophisticated task because the film's thickness was about 0.2 - 0.5 micrometers .
