Abstract: (732 Views)
Raman spectroscopy as a powerful sensing method has attracted the attention of many researchers. Disadvantages of this method are low cross-section of Raman scattering and weak Raman signal. Several methods have been proposed to amplify the Raman signal, including fiber-enhanced Raman spectroscopy. In this method, by increasing the optical path length, the interaction of the laser light with the sample increases and the Raman signal is amplified. Hollow core fibers and capillary tubes are often used. In capillary tubes, in order to Total internal reflection, liquids with a refractive index higher than the refractive index glass of the capillary tube are used. In this research, capillary tubes containing cyclohexane have been used as a target sample with a refractive index lower than glass, in different dimensions, as a waveguide. The effects of capillary tube diameter and length on increasing Raman signal were also investigated.
