Abstract

A pump-probe technique was used to measure the shock wave velocity generated by laser-induced optical breakdown in water. The transient shock pressure field was mapped using the measured shock velocities, together with the equation of state of water and the jump equations. We find that the calculated shock pressures near the breakdown region are in the kbar range and scale as hr2. Depending upon the energy of the laser pump pulse, typically 3 to 15 mJ, the shock wave dissipates within 300-500 1um.
