Abstract. Simulation results describing the heat source formation and optical properties modification of the zinc oxide sol-gel films with silver nanoparticles by the series of ultrashort laser pulses in heat-accumulation mode are demonstrated. Based on presented relationships between laser exposure modes, the optical characteristics of films and the properties of nanoparticles in them, the possibility of predicting the optical properties of the composite materials is shown.
