title: [Influence of laser power and incident angle as well as testing distance on laser inducted breakdown spectroscopy (LIBS) technology for spectroscopy diagnosis and multi-element analysis].
abstract: Laser inducted breakdown spectroscopy (LIBS) technology has been used widely for the multi-element analysis of different samples and also an effective way to realize the spectroscopy diagnosis applied to calculating the electron temperature and vibration-rotation temperature etc of some certain elements. It is a highly effective measurement for its non-contact and nondestructive on-line analysis with the help of a high-speed response CCD camera. In the present paper, the authors tested an alley though LIBS technology to determine its elements in terms of species and quantities and also discussed some influences of the incident angle and the power changes of the laser beam as well as the measurement distance changes on the experimental results and and gave appropriate theoretical explanation.
