Using pulses of multifrequency stimulated Raman scattering (SRS) in calcite, nonlinear photoluminescence in a stilbene molecular crystal is excited. When multifrequency SRS is excited by the radiation of a Nd 3+ : YAG laser with a wavelength of 1064 nm, eleven anti-Stokes components are observed in the visible spectrum with an average frequency shift of 1086 cm -1 between them. Using the second harmonic of the Nd 3+ : YAG laser radiation allowed three anti-Stokes and four Stokes components to be recorded. The large spectral range of the frequency comb facilitated effective reduction in the duration and increase in the intensity of the radiation pulse of multifrequency SRS.

方解石单晶中光的多频受激拉曼散射

使用方解石中的多频激发拉曼散射（SRS）脉冲，可以激发二苯乙烯分子晶体中的非线性光致发光。当用波长为1064 nm的Nd 3+：YAG激光器的辐射激发多频SRS时，在可见光谱中观察到11个反斯托克斯分量，它们之间的平均频移为1086 cm -1。使用Nd 3+：YAG的二次谐波，可以记录三个反斯托克斯和四个斯托克斯分量。频率梳的大频谱范围有助于有效减少持续时间并增加多频SRS辐射脉冲的强度。
