Demonstration of uniform illumination on target by focusing high power laser beam
The effect of a focusing system which is composed of a spherical regular hexagon lens array and an aspherieal principal focusing lens used for improving the illumination uniformity of the high power laser on the target surface has been demonstrated experimentally. We report here a excellent result that the flatness of the laser driven shock wave was improved obviously when this focusing system was used at laser beam power of 1012 W.
