摘要:

我们利用逆拉曼散射和溶剂化电子吸收进行定量表征的能量损失和电离动力学在水中紧密聚焦的近红外飞秒脉冲。实验数据和数值模拟之间的比较表明,水的电离能为8 eV,而不是通常使用的值6.5 eV。我们还介绍了一个方程的拉曼增益适用于超短脉冲,验证了我们的实验程序。

英文摘要:

We exploit inverse Raman scattering and solvated electron absorption to perform a quantitative characterization of the energy loss and ionization dynamics in water with tightly focused near-infrared femtosecond pulses. A comparison between experimental data and numerical simulations suggests that the ionization energy of water is 8 eV, rather than the commonly used value of 6.5 eV. We also introduce an equation for the Raman gain valid for ultra-short pulses that validates our experimental procedure.
