摘要
A numerical solution of the two-temperature model has been performed up to the double-pulse femtosecond laser heated metal target. The two-temperature model is used to analyze the double-pulse laser with the following major conclusions. We confirm the distinctly different results on the single pulse and double pulse. The double-pulse laser heated lattice temperature is higher than the single pulse. Through the Boltzmann equation, we estimate the variation of the emission enhancement. At the same time, this experimental result is qualitatively similar to the theoretical result. (C) 2011 Elsevier B.V. All rights reserved.
