About non-uniformity smoothing using foam substrate
Original language description
The shock behavior for complex foam-Al targets have been investigated experimentally and numerically analyzed. By splitting the laser beam in two equal parts with a prism we could obtain two focal spots with a diameter about 30?m separated by about 100?m, thus producing very large irradiation non-uniformity, a priori very difficult to smooth out. One of the main results is the difference in time-resolved rear-side self-emission images obtained with the streak camera for aluminum and aluminum-foam targets. If in the first case (Al target) the two shocks generated by the two laser spots emerge separately on target rear side. In the second case (Al+foam target) the shock breakout are quite larger and the two emission region merge with each other, so thatthe central part becomes e ven brighter than the regions corresponding to the two spot centers.
