UV Planar laser induced fluorescence images of carbon dioxide in high pressure laminar flames (5-60 bar) with excitation wavelength at 226.03 nm are presented. Carbon dioxide images are extracted from interference signals using numerical computational fitting in a CH4/air flat-flame. Signal varies linearly with pressure and laser fluence. Detection is via a broad (200-450 nm) continuum LIF signal with a faint superimposed band structure, which has recently been attributed to laser induced fluorescence from electronic excitation of carbon dioxide. Positive linear dependence of this LIF signal intensity versus pressure and excitation energy offer unique diagnostic opportunities for high pressure flames.
