The surface of Ti/FTO composite films prepared with the direct current magnetron sputtering method is irradiated by a nanosecond pulsed laser with a wavelength of 532 nm. The effects of laser energy density on surface morphology, crystal structure, optical and electrical properties of the films are studied. The results show that the irradiation of films with appropriate laser energy density has the annealing effect on film surfaces, which on the one hand promotes film grain growth and eliminates partial crystal defects, and on the other hand, gives rise to the transformation of Ti layer to TiO2 layer via oxidation, and finally improves the overall photoelectric property of the films.
