摘　　要：采用诱导空间非相干(FEISI)的平滑方法结合传递傅里叶面的技术,建立了一套平滑化六束角多路系统。该系统输出总能量158 J,能量稳定度约4%,输出脉冲宽度25 ns,靶面有效焦斑直径400μm,焦斑均匀性1.6%,激光功率密度3.7×1012W/cm2。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 × 10^12 W/cm^2.
