The laser‐induced plasma shock waves and related cavitation bubbles on an aluminum surface underwater have been experimentally studied with a high‐sensitivity optical deflection system. The expansion of the shock wave pulse duration, the positions where shock waves attenuate to acoustic transients, the maximum bubble radii, and the bubble collapse center shifts have been determined experimentally. A high‐pressure wall behind the bubble has also been observed with this deflection system. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 25: 307–311, 2000.
