Abstract
We constructed an ultrafast stroboscopic photographic arrangement. A PMMA surface was ablated by an ArF excimer laser, and pictures were taken by two delayed, subnanosecond dye laser pulses. We measured the propagation velocity as a function of time, and found a good agreement with shock wave theory. The pressure behind the shock front can be as high as 1939 atm.. In the first phase of the ablation process a head wave could be seen, presumably generated by the lightest fragments, that are ejected with the highest velocity, perpendicular to the surface.
