Development of new angular multiplexing for “Heaven Ⅰ”
-
Abstract
Adopting the echelon-free induced spatial incoherence (EFISI) technique and image relay technique, a new angular multiplexing with smoothing function was built. The total energy of 6 beams is 158 J, the stability of energy is 4%, the pulse duration is 25 ns, the effective diameter of focusing spot is 400 μm, the ununiformity is about 1.6%, and the power density on the target is about 3.7×1012 W/cm2.
