摘要

利用传统的z扫描技术,研究了飞秒激光脉冲重复频率对纯有机液体双光子吸收和非线性折射的影响。这样的研究提供了一种方法来确定光-物质相互作用的性质,明确地使识别线性与非线性体制成为可能。基于光-物质相互作用的类型,我们确定了有机液体的热负荷耗散时间。实验结果与理论计算的热负荷耗散衰减时间吻合较好。

Effect of femtosecond laser pulse repetition rate on nonlinear optical properties of organic liquids
The effect of the repetition rate of femtosecond laser pulses on the two-photon absorption and nonlinear refraction of pure organic liquids is presented using the conventional Z-scan technique. Such a study provides a way to determine the nature of light-matter interaction, explicitly enabling the identification of the linear versus nonlinear regimes. Based on the type of light-matter interaction, we have identified the thermal load dissipation time for the organic liquids. Our experimental results are in good agreement with the theoretically calculated decay time for the dissipation of thermal load.
