In this study, we investigated both experimentally and numerically two-photon laser-induced fluorescence from carbon monoxide (CO-TPLIF) in order to determine the applicability of this technique for imaging CO concentration in aircraft combustion chamber. Experiments were carried out in an optical –accessible gas cell under various conditions of temperature (300-900 K), pressure (0.1-3 MPa) and carrier gas (N2, air, He). Fluorescence intensity decreases as temperature and pressure increase. Comparison between simulations and experimental results show good agreement
