【Abstract】 The concept of shock temperature in the interaction betweer femtosecond laser pulses and a solid target is defined.The relationship between the shock temperature and other physical parameters in the process of femtosecond laser ablation of aluminum and copper targets is discussed.Absolute values of shock temperature are calculated by means of a two-temperature model.Shock temperature is calculated distribution based on the non-Fourier heat conduction model.Result of this investigation plays an important role in the secure femtosecond laser processing of energetic materials.更多还原
