文摘
Pump-probe technique is employed to investigate the dynamic process of shock wave in water induced by femtosecond laser pulse. The time resolved shadowgraphs and holograms were obtained experimentally, and the 2-dimensional phase maps were reconstructed from holograms. From the analysis of the phase maps, the evolution process within the laser–water interaction region was described and the formation mechanism of the shock wave was discussed.
