In this work, tin doped copper oxide films have been manufactured by PLD. The films were examined by UV-VIS-NIR spectrophotometer, X-ray diffraction and their thickness by utilizing optical interferometer technique. Pulsed Nd:YAG laser was used for arranging CuO0.9:Sn0.1 on a glass substrate with varying number of laser pulses at a substrate temperature (673K). The optical properties of as-grown film, for example, optical transmittance, absorption coefficient, refractive index, extinction coefficient and energy gap have been measured tentatively and the influences of a number of laser pulses on it were studied. An inverse relationship between energy gap and the number of laser pulses was observed.
