Samenvatting

Results are given of spectrally as well as temporally resolved measurements of Na-fluorescence in an H2-O2-Ar flame at 1 atm (T = 1760 K). The Na-atoms were excited with a spectrally broadband pulsed dye laser, tuned to resonance. The existence of radiation-power broadening of the Na-D lines, due to interaction of the Na-atoms with the intense (broadband) resonant laser field, has been established for the first time. Quantitative agreement is obtained between a simplified theory and experimental results if we account for the (measured) spatial inhomogeneity of the laser beam.
