【Abstract】 The laser beam from a pulsed tunable dye laser is tuned to the resonance line of sodium 3²S_1/2-3²P_1/2(（?）=16961cm^-1) to excite the sodium atoms in a hydrogen-acetylene flame. Sodium is thus sensitively detected by nonresonance fluorescence induced by saturated excitation of sodium atoms produced by the laser beam. The detection limit reached is 10^-11 g/ml.更多还原
