利用实验的方法研究了甲基红掺杂碳纳米管悬浮液对波长为532 nm激光的光限幅效应.分析了样品厚度和入射激光重复频率对光限幅特性的影响，并与纯碳纳米管悬浮液的光限幅特性进行了比较.实验结果表明，对于线性透过率为60%（500 nm）的碳纳米管悬浮液，掺入甲基红后其沉淀速度明显减慢，限幅阈值由250 μJ降低为200 μJ；对于2和5 mm 厚度的样品，掺杂甲基红使碳纳米管悬浮液的箝位输出激光脉冲能量分别由45和20 μJ降低为35和9 μJ.

The optical limiting effect of Methyl-red dye doped suspended carbon nanotube mixture on 532 nm lascr lighter is studied in experiment. The experiments were carried out with samples of different thickness radiated by laser with different repetition frequency, and the results are compared with the results got from pure suspended carbon nanotubes. The results showed that, if the suspended carbon nanotubes with 60% transmission is doped with some Methyl-red dye, its solubility can be improved and the input limiting threshold decreases from 250 μJ to 200 μJ. The clamped output energies for samples with 2 mm and 5 mm thickness decrease from 45 and 20μJ to 35 and 9 μJ, respectively.-
