The key factors for successfully experiment are the optimum design of the system parameter and improved precision of fabrication, when the two-dimensional orthogonal segmented wedge array (SWA) optical system is used to generate a uniform laser focal profiles on the target with focus width of several hundred microns and a high energy utilization factor. A nine-element small-focal-spot crossed SWA system was successfully fabricated with optimum design of the system parameter and strict control precision of fabrication. The focal-spot characteristics are measured.
