This study describes the measurement of CO2+N2 mixture flow concentration using CARS (Coherent anti-Stokes Raman Scattering). CARS is generated by two excitation beams of different wavelength, which excite the vibrational motion of the molecule. This method can selectivity measure the molecule of gas, which means that the non-intrusive measurement is achieved. However, the non-resonant background noise has been generated from channel walls. The objective of this study is to reduce the influence of the background noise by varying diameter of excitation beam in order to energy densities of excitation beams transmitted through the channel walls.
