Therefore, in this research AZO thin film was fabricated by using sol gel method and then annealed at 500°C in an air environment for 2 hours. Finally, Azo thin films irradiated by different laser wavelengths at nanosecond, ArF excimer laser at 193nm, and femtosecond Ti:Sapphire laser which is tuned at 800nm. It can be seen the great positive impact of laser irradiation on the electrical conductivity of the samples.
