For the first time, stimulated Raman scattering (SRS) was detected in rectified ethanol upon excitation by ultrashort (55 ps) pulses of a YAG:Nd³⁺ laser operated at a wavelength of 355 nm. SRS of light is observed in the form of several Stokes components on the symmetric mode of the CH₃ group. The large Raman shift of the Stokes components, as well as the relatively high gain of stimulated Raman radiation, makes it possible to effectively use ethanol for the conversion of laser radiation into different spectral ranges.

皮秒激光激发下乙醇中的多频受激拉曼散射

在 355 nm 波长下操作的 YAG:Nd ³⁺激光的超短 (55 ps) 脉冲激发后，首次在精馏乙醇中检测到受激拉曼散射 (SRS) 。在 CH ₃基团的对称模式上以几个斯托克斯分量的形式观察到光的 SRS 。斯托克斯分量的大拉曼位移以及受激拉曼辐射的相对高增益，使得有效地使用乙醇将激光辐射转换为不同光谱范围成为可能。
