Resonance enhancement of coherent anti-Stokes Raman scattering due to the proximity of the laser frequencies to an electronic transition has been demonstrated for dilute solutions of diphenyloctatetrane in benzene. The Raman contribution to the third order susceptibility is shown to be complex near an electronic resonance and the resulting features of the coherent anti-Stokes Raman scattering spectra are discussed in detail. This work represents one step in the demonstration that the high signal to noise ratio, fluorescence rejection, and low average power levels of the coherent anti-Stokes Raman scattering experiment can be used to advantage in Raman studies of dilute solutions and materials of biological interest.
对于二苯基辛四烯在苯中的稀溶液，已证明由于激光频率接近电子跃迁而导致的相干反斯托克斯拉曼散射的共振增强。结果表明，在电子共振附近，拉曼对三阶磁化率的贡献是复杂的，并详细讨论了相干反斯托克斯拉曼散射光谱的最终特征。这项工作是迈向如下证明的一步：相干反斯托克斯拉曼散射实验的高信噪比、荧光抑制和低平均功率水平可有效地用于对稀溶液和具有生物学意义的材料进行拉曼研究。
