A new laser-induced breakdown spectroscopy (LIBS) enhancement method utilizing interaction between microwave radiation and laser-induced plasma is proposed to analyze the element s in rice.The laser induced plasma from the rice surface is generated by using a nanosecond pulsed 1064nm beam of Nd:YAG laser irradiate the rice,and microwave radiation is generated by a magnetron at frequency of 2.45GHz.The emission lines of the main elements in rice,such as carbon (C),magnesium (Mg),calcium (Ca), silicon (Si) and cadmium (Cd),are identified according to the national institute of standards and technology database of atomic emission at waveband from 210nm to 480nm.It is found that the relative intensi ties of the emission lines of microwave assisted-LIBS (MA-LIBS) are stronger t han conventional LIBS by making a comparative analysis of the spectra of laser i nduced breakdown plasma and microwave assisted-laser induced breakdown plasma.Up to 21times enhancement on different spectral lines is achieved.The results in this paper have an important reference and significance for enhancing the intensities of LI BS emission,and provide a new way to improve the LIBS detection sensitivity.
