Abstract
A shock wave is driven by a laser pulse of 1.2 ps duration (FWHM), with the intensity of ∼1014 W/cm2 at 785 nm, irradiating a 500 nm thick aluminum foil. A chirped laser pulse split from the main pulse is used to detect the shock breakout process at the rear surface of the target based on frequency domain interferometry. The mean shock velocity determination benefits from the precise synchronization (<100fs resolution) of the shock pump and probe laser pulses, which is calculated from the time the shock takes to travel the 500 nm thick aluminum. The released particle velocity determination benefits from the chirped pulse frequency domain interferometry. The average shock velocity is 15.15 km/s and the shock release particle velocity is 15.24 km/s, and the corresponding pressure after shock is 3.12 Mbar under our experimental condition.
