The temporal and spatial evolution of the depleted neutral atom density following laser-enhanced ionization in laminar flow flames has been used to characterize the flow velocity of the flame gases. This technique utilizes a low power cw dye laser and a low sodium seed density (1011 to 1012 atoms/ml). The flow velocity can be measured to better than 2% in standard analytical burners.
