We have demonstrated that the laser-enhanced ionization (LEI) technique can be used to determine the efficiency of atomization of metal elements in an atmospheric acetylene/air flame. We have derived a useful relation between the time-integrated LEI signal and the total free atom number density in a flame. We determine the efficiency of atomization of ∼0.13–0.37 for the lithium element and of ∼1.0 for the sodium element. Our results agree well with AA measurements reported previously.
