Paper Abstract

Self-absorption is used in laser induced breakdown spectroscopy to obtain quantitative analytical information. In this approach two plasmas are generated with a laser pulse that is split into two beams separated by a few millimeters and incident on the target material. One of the beams generates plasma that acts as the light source analogous to that used in standard atomic absorption spectroscopy, while the other generates plasma that is used as the analyte. The lines emitted from the light source plasma are absorbed while passing through the analyte plasma. This technique was applied to Cu- Zn samples with different Cu/Zn concentrations. The results show that the strongly self absorbed Cu 324 nm and 327 nm lines can be effectively used to probe the Cu concentration, while the Cu 330 nm line does not show strong selfabsorption.
