自出现第一台激光器和稍后提出用激光引发热核聚变反应四十年来,人们对热核聚变规划实现的可能性有了某些变化。显然,它的实现技术难度很大,虽然原始思想非常简单:有必要的光通量功率密度,有最易点火的燃料——氘氚混合物。而且引发反应所需的激光脉冲能量规模本身也不是非常巨大,完全能够达到。但是今天激光热核聚变的问题是,用什么合适方法实现热核靶反应“点火”。 There has been some change in the likelihood of a thermonuclear fusion program being implemented since the first laser appeared and later proposed to initiate a thermonuclear fusion reaction with a laser. Obviously, it is technically difficult to implement, although the original idea was very simple: the luminous flux power density necessary, with the most easily ignitable fuel-deuterium-tritium mixture. And the amount of laser pulse energy required to initiate the reaction is not huge enough by itself. But today the problem with laser thermonuclear fusion is the “ignition” of the thermonuclear target reaction by any suitable method.
