摘要: Abstract The nonlinear optical absorption, refraction and switching behavior of Zinc phthalocyanine (Zn(II)Pc) thin films are reported. Z-scan technique is employed to study the absorption with nanosecond pulses Nd:YAG laser at ∼532 nm. Optical dye studied using pump-probe ∼5 ns ∼532 nm as pump beam ∼632.8 nm cw He-Ne probe beam. attributed excited state (ESA) by molecules. Probe modulation increasing intensity also investigated.
