摘　　要：利用飞秒脉冲激光,研究了二硫化碳(CS2)、铜酞菁(CuPc)/二甲亚砜(DMSO)和CuPc/CS23种溶液在蓝光波段的光限幅效应。实验结果表明,这3种溶液在蓝光波段下由于具有非线性吸收特性均表现出较好的光限幅性能,其中,CuPc/CS2溶液的光限幅性能最好,光限幅阈值为0.585mJ·cm^-2,说明在具有光限幅效应的溶剂中加入具有光限幅性质的材料可以达到较好的光限幅效果。The optical limiting effects of carbon disulfide(CS2),copper phthalocyanine(CuPc)/dimethylsubsid(DMSO),and CuPc/CS2 solutions in blue band are studied by using femtosecond laser.The experimental results show that these three solutions show better optical limiting response at 400 nm because of nonlinear absorption,among which CuPc/CS2 solution has the best optical limiting response,and its optical limiting threshold is0.585 mJ·cm^-2.The results show that the better optical limiting response can be achieved by adding a material with optical limiting property into the solvent with an optical limiting effect.
