含偶氮非线性光学生色团取代炔的合成及光限幅性能研究
Synthesis and optical limiting properties of a novel subs tituted acetylene with azobenzene nonlinear optical chromophore
【摘要】 合成一种新的偶氮苯非线性光学生色团取代乙炔,用红外光谱,元素分析,核磁共振对其进行了表征,利用波长1064nm脉冲宽度40ps的激光,对该化合物光学性能进行研究,结果显示该化合物的THF溶液对40ps的1064nm脉冲激光呈现出较好的光限幅性能,其限幅阈值为235.9GW cm2。
【Abstract】 A new substituted acetylene with an azobenzene nonl in ear optical chromophore has been synthesized and characterized by IR, element an alysis and NMR. Its optical properties in THF solution were measured with a Q-sw ithed ns/ps Nd:YAG laser system continuum with pulse width of 40 ps at 1064nm wa velength. A dilute solution (4 mg/ml) of the substituted acetylene with an azobe nzene chromophore effectively limited the intense laser pulse.
