We investigate pulse duration and wavelength effects on the optical limiting behavior of single-wall carbon nanotubes suspended either in chloroform or in water. The principal optical limiting effect in carbon nanotube suspensions is nonlinear scattering that is due to heat transfer from particles to solvent, leading to solvent-bubble formation and to sublimation of carbon nanotubes. We report on nonlinear transmittance measurements for pulse durations ranging from 3 to 100 ns and for wavelengths from 430 to 1064 nm. The dependence of optical limiting behavior on pulse duration and wavelength is analyzed and discussed in terms of nonlinear mechanisms.
我们研究了脉冲持续时间和波长对悬浮于氯仿或水中的单壁碳纳米管光学限幅行为的影响。碳纳米管悬浮液中的主要光学限幅效应是由于颗粒向溶剂的热传递导致的非线性散射，从而导致溶剂气泡形成以及碳纳米管升华。我们报告了脉冲持续时间从3纳秒到100纳秒、波长从430纳米到1064纳米的非线性透过率测量结果。从非线性机制的角度分析和讨论了光学限幅行为对脉冲持续时间和波长的依赖性。
