Abstract
Nonlinear optical properties of cover glass/ZnS-SiO2(130nm)/AgOx(15nm)/ZnS- SiO2(40nm) is studied by using a focused continuous-wave (CW) He-Ne laser ((lambda) equals632.8 nm) and a pulse laser ((lambda) equals532 nm, pulse width 0.7 ns, repetition rate 15.79 kHz) with a confocal Z-scan system. The transmission confocal Z-scan shows that the sample undergoes a phase transition at different incident intensities when the light source is changed. High reflectance happens at the focusing on AgOx film. The phase transition of the sample at higher incident laser power is due to silver oxide dissociating by the laser heating process.
