Quantitative atomic absorption measurements on transient plasmas induced by a Q-switched laser beam were made using pulsed hollow cathode lamps. Calibration curves were obtained for 0.002 to 0.15% Cu in an aluminum alloy and 0.013 to 0.124% Mn in graphite pellets. The dependence of the atomic absorption characteristics upon changes in laser energy and upon atmospheric gas and pressure is discussed.
