设在里弗莫尔的“国家点火装置”包括许多尺寸达1m的激光放大器和光学件,在2~3mm直径的含氘氚混合物靶丸中获得核聚变点火。“国家点火装置”有192束线,每路都配有强闪光灯和高能量电容器组,大量非线性光学晶体,可以产生最强的紫外激光脉冲。过去一个束线产生21kJ红外脉冲(1064 The National Ignition Facility at Livermore includes many laser amplifiers and optics up to 1m in size and nuclear fusion ignition in 2 to 3mm diameter deuterium-tritium mixed target pellets. The National Ignition Unit has 192 beam lines, each equipped with a strong flash and high-energy capacitor bank and a large number of nonlinear optical crystals that produce the strongest UV laser pulses. A beamline in the past produced 21 kJ infrared pulses (1064
