In this paper, the technology of laser induced breakdown spectroscopy (LIES) is discussed in the application area of plasma's temperature detection. The principle of LIBS is interpreted, and the experiment using LIBS to detect the plasma's temperature is implemented also. When the plasma reaches local thermal balance, the purpose of plasma's temperature detection by LIBS can be achieved using the method of the relative intensity detection of the plasma's characteristic spectrum. The experiment result shows that it is a very convenient and quick method to use LIBS in the temperature detection of plasma, and it is also very useful in practice.
