To describe femtosecond laser interaction with metal, the Double-Temperature Equation(DTE) was formatted simply. The electron-lattice couple time is determined through the numerical simulation, which is compared with long pulse.

• 对金属材料，通过数值分析约化后的双温模型，对飞秒激光与金属材料相互作用过程进行研究，确定了电子与晶格的耦合时间，并与长脉冲情形进行比较，同时又考虑了脉冲串对材料作用结果的影响；
