荧光物质对受激拉曼散射的影响
|
摘要
荧光在受激拉曼散射中能发挥良好的外部种子作用,可以极大幅度降低受激拉曼阈值、增加散射模式的强度.将溶解了荧光物质的CS2溶液作为液芯光纤的芯液体进行荧光增强受激拉曼散射研究.结果表明,很小能量(1.86mJ)的激光激发就能获得较强的Stokes和anti-Stokes拉曼光.以荧光光谱范围较小的Rhodamine B作为荧光种子,由于Rhodamine B吸收与荧光的共同作用,只获得了强度较高的一阶anti-Stokes谱线和强度较低的一阶Stokes谱线；以荧光光谱范围很大的β-carotene作为荧光种子,由于β-carotene的双荧光特性和三阶非线性光学系数较大的性质,很小的泵浦能量就获得了七阶Stokes光谱.因此可以选用不同光学性质的荧光种子来选择性增强受激拉曼散射的某一散射模式。
The fluorescence is demonstrated a well out-seeding effect in the stimulated Raman scattering(SRS), which can drastically low the SRS threshold and enhance the intensity of scattering-mode. The solution of fluorescent seeding in CS2 is used to study of the fluorescence enhancement SRS in liquid core optical fiber(LCOF). The results demonstrate that the stronger intensity of Stokes and anti-Stokes can be observed at low pump energy. The RhodamineB of narrow fluorescent spectrum is used, the high intensity of first-order anti-Stokes line and low intensity of first-order Stokes line are obtained because of the absorption and fluorescence effect of Rhodamine B; theβ-carotene of broad fluorescent seeding is used, the seventh-order Stokes lines are obtained at low pump energy because of the double-fluorescence and larger third-order nonlinear optical coefficient ofβ-carotene. So, we can selectively enhance the scattering-mode of SRS according to the different optical characteristics of fluorescent seeding.
