Abstract

The concepts of shock pressure and shock temperature in the interaction of femtosecond laser pulse and solid target are defined. Then the relationship between the shock pressure and other physical parameters in the process of femtosecond laser ablation of aluminum, copper, and silicon targets are discussed. Absolute values of shock pressure are calculated by means of the time-resolved pump detection shadow-graph. Result of this investigation plays an important role in the secure femtosecond laser processing of energetic materials and the femtosecond laser propulsion technology.
