Abstract
In this paper is proposed a laser-based system to perform a real time Raman spectroscopy applied to in-line combustion diagnostic. This approach is widely used for solid and liquid analysis; the problem related to gas samples is the low density since the amount of Raman scattering is proportional to the quantity of molecules in the matter-light interaction region. Our setup is based on a multi-pass cell (designed to increase the collected signal) that allows high-frequency acquisitions.
