In this paper, an optodynamic method for measurement of the shock wave front is presented. Two dimensional scanning was performed to determine the time-of-flight for each particular position of the probe beam. The interferometer part of the setup was used to accurately pinpoint the location of the laser induced breakdown. From the time-of-flight data we calculated the velocity field and found two regions of propagation of acoustic waves in water: a supersonic velocity region and a sonic velocity region. From the velocity the pressure amplitudes were calculated
