Paper Abstract

Femtosecond-laser-induced shock waves in aluminum film deposited on alpha-quartz were generated at a repetition of up to ten shocks per second. Using ultrafast time-resolved microscopy of shock waves in different thickness of aluminum films, the shock velocity propagated in aluminum was measured to be 9.0±0.7 km/s. With shock wave equations of state, shock pressures in aluminum and α-quartz were calculated to be 66(±15) GPa and 56(±15) GPa respectively, and final temperatures in aluminum and alpha-quartz were calculated to be 281 °C and 104 °C respectively.
