Abstract

The results of investigation of laser emission plasma exited by burst of laser pulses under normal atmospheric conditions are presented. It was showed that the spectra of laser emission plasma significantly depends on characteristics of laser burst. The proper choice of regime of laser source of excitation leads to increasing of signal to background ratio due to both spatial separation of area continuous radiation and area of linear spectrum and increasing of intensity of atomic lines. So the detection limit of trace element at laser induced breakdown spectroscopy (LIBS) may be improved essentially. The physical explanation is proposed.
