摘要
应用Z扫描技术,在波长为532nm、脉宽为8ns条件下,对一种新型亚酞菁配合物三-α-(2,4-二甲基-3-戊氧基)溴硼亚酞菁的三阶非线性光学特性进行了研究,结果发现,该新化合物有较强的反饱和吸收(β=3.7×10-10m/W)效应和非线性自聚焦折射效应(n2=7.2×10-11esu),其三阶非线性极化率χ(3)=1.1×10-11esu.分析了溴硼亚酞菁配合物特殊的锥形分子结构和重原子溴的轴向配位等因素对其三阶非线性光学性质的重要影响.
The third-order nonlinear optical properties of a new subphthalocyanine complexe (bromo[tri-α-(2,4-dimethyl-3-pentyloxy) subphthalocyanine] boron) was studied by Z-scan using 8ns laser pulses at 532nm. It was found that the compound shows a strong reverse saturation absorption (β = 3.7×10^-10 m/W) and nonlinear self-focusing refraction effects (n2 = 7.2×10^-11 esu). The third-order nonlinear susceptibility (χ^(3)) is 1.1×10^-11 esu. The effects of cone-chaped molecular structure and axially heavy-atom (Br) substitution on third-order nonlinear optical properties are also discussed.
