Abstract

In this paper, we report a hollow-core fiber as the micro liquid sample detection probe to transmit the exciting light and collect the Raman signal. In order to optimise Raman spectrum measurement system, various parameters were experimentally studied, such as the core diameter and length of the hollow-core fiber, the height of the liquid sample, the relationship between the height of liquid in hollow fiber and the intensity of Raman characteristic peak and the means to enhance the Raman scattering so on. Since this Raman detection method employed a hollow-core fiber to collect sample, the sample required is small in volume, it is easier to use the detection system in the practical applications, It provides an effective method for the fast Raman detection system.
