Abstract:
Laser-induced breakdown spectroscopy (LIBS) has been used to detect the elements of 2519A aluminum alloy by Nd : YAG laser in the present paper. The atomic spectral lines of Al and Cu were observed using a portable spectrometer. The impacts of lens-to-sample distance, probe angle, laser pulse energy, observation height and ambient pressure on the line intensities were studied. The results show that all these experimental parameters have great influence on the precision of LIBS such as line intensity, signal to background ratio and repeatability. Finally, the best results can be observed by using the optimum experimental conditions.
