Mach-Zehnder interferometry was used to study the pressure waves generated by the surface ablation of water with ultrashort laser pulses in the 140 fs-10 ps duration range. Formation and propagation of spherical and in ablation with longer pulses, combination of spherical and cylindrical pressure waves were observed. Laser ablation of the surface of water generates plasma that allows light transmission into the bulk of only the leading edge of the laser pulse.
