The laser-induced fluorescence excitation spectrum of jet-cooled CoO molecules has been studied in the range of 540-725 nm. Beside all the parallel-polarized and perpendicular bands observed previously by Barnes and co-workers [M. Barnes, D.J. Clouthier, P.G. Hajigeorgiou, G. Huang, C.T. Kingston, A.J. Merer, G.F. Metha, J.R.D. Peers, S.J. Rixon, J. Mol. Spectrosc. 186 (1997) 374-402], 59 new bands have been recorded. Rotational constants have been derived and three new vibrational progressions identified. These three new band systems have been designated [13.99](4)Pi(5/2)-X-4 Delta(7/2), [14.20](4)Pi(5/2)-X-4 Delta(7/2) and [15.85](4)Pi(5/2)-X-4 Delta(7/2). In addition, lifetime measurements have been carried out for most of the bands under collision-free conditions.
