摘　　要：利用实验的方法研究了可溶性碳纳米管对波长为1064和532nm激光的光限幅效应.分析了在不同的样品浓度、不同的样品厚度情况下可溶性碳纳米管的光限幅特性,并对溶剂也进行了光限幅实验.实验结果表明,在各种情况下可溶性碳纳米管对1064和532nm激光具有较强的光限幅特性.The optical limiting effect of solubilized carbon nanotubes on 1064 and 532 nm laser is studied in experiment. The experiments are carried out with samples of different thickness and concentration, and the optical limiting experiments are also carried out with pure solvent ( chloroform) in order to confirm that the optical limiting effect is due to carbon nanotubes. The results showed that the solubilized carbon nanotubes have good optical limiting characters to both 1064 and 532 nm laser.
