Laser fluorescence spectroscopy is a useful technique to determine the density and the flux of metallic atom impurities in the edge region of Tokamaks. A new scheme to measure the Doppler profile of impurity atoms by a single laser shot is proposed. The frequency of dye-laser emission is rapidly scanned across the Doppler profile during the laser action in the order of microseconds. A flashlamp-pumped dye laser is tuned by a piezoelectrically scanned etalon, and a scanning range of 60 pm is obtained with a resolution of 3 pm at lambda approximately=600 nm. Fluorescence line profiles of Na atoms are determined with a resolution of less than 1 pm. Several problems of Tokamak measurements are briefly discussed.
