This paper reports on an anomalous spatial distribution of temporal and spectral behaviour which has been observed when the temporal profile of an excimer laser-pumped, pulsed dye laser beam was analysed. Substantially different shapes were found at selected spatial locations within the same laser beam. This effect was demonstrated by comparing the laser excitation and fluorescent waveforms of gallium and lead atoms in the inductively coupled argon plasma. The recognition of such anomalous behaviour is essential for a correct interpretation of some time-resolved fluorescence and ionisation experiments.
