Pulsed, supersonic molecular beams and pulsed lasers are particularly well matched tools when combined in molecular reaction dynamics studies. Salient features of an experiment using two pulsed molecular beam sources, a pulsed ultra-violet laser for creating reactive atoms by laser ablation and a pulsed dye laser for performing laser-induced fluorescence detection of the products are described. Differences with steady-state molecular beam experiments are outlined with respect to the following points: facility of inverting the data, possibility of obtaining high signal-to-background ratios and wide ranges of collision energy. These points are illustrated with some results concerning the reactions:C(n3P)J+NO(Xπr2)CN(X2Σ2)+O(n3PJ),C(n3PJ)+N2O(X1Σ+)CN(X2Σ+)+NO(Xπr2)and Mg(n1S0)+N2O(X1Σ+)MgO(X1Σ+)+N2(X1Σg+)
