Solid-state dye-doped polymers are attractive alternatives to the conventional liquid dye systems. In this paper, the third order nonlinear optical property of Sudan III, an azo dye in solvents and dye doped polymer films measured using the Z-scan technique is reported. Multiple diffraction rings were observed when the dye doped in both the liquid and solid media was exposed to a diode-pumped Nd:YAG laser at 532nm.
固态染料掺杂聚合物是传统液体染料体系颇具吸引力的替代物。本文报道了采用Z扫描技术测量的溶剂中的偶氮染料苏丹III以及染料掺杂聚合物薄膜的三阶非线性光学性质。当液体和固体介质中掺杂的染料暴露于532nm的二极管泵浦Nd:YAG激光时，观察到了多个衍射环。
