| Abstract: | To acquire the temperature of laser plasma with high spatial and temporal resolution, a new method based on the two line method for measurement of plasma temperature is proposed. The principles and realization of the method are described. Results with the spatial resolution of 137.2μm and the temporal resolution of 500 ns are obtained while the temperature of plasma is 104 K. The results indicate that the high temporal and spatial resolutions can be acquired by using this method. |
