Abstract
This paper analyzes the micro-mechanism of interaction between femtosecond laser and one dimension material. It gets the figure of temperature change with time by calculating the Two Temperature Equation(TTE) in the process of the laser ablation. And it presents the surface characters of metal material. Additionally, the plasma is generated when the temperature of ion subsystem is far higher than the melting point of copper metal. The paper can give the laser ablation threshold by the numerical calculation. It will help the researchers ensuring the laser fluence for preparing the copper film better.
