本文评述了帕尔斯激光聚变实验装置最近进行的激光驱动氘核聚变实验。它们得益于高反应截面和大量的多MeV氘核，这些氘核来自于强度为3× 1016 W cm−2的厚CD2靶。在已报道的实验中，在一个投捕器靶配置中通过7Li（d，n）8Be和11B（d，n）12C反应产生能量高达16MeV的快聚变中子。当使用大面积的CD2箔作为次级捕获靶时，2H（d，n）3He反应的总最大中子产额增加了约5倍，从4× 108增加到2× 109。这一结果表明，大多数具有足够动能进入聚变反应的氘核从主靶发射到真空中。
Recent experiments at the laser facility PALS focused on the laser driven fusion of deuterons are reviewed. They benefit of high reaction cross-sections and of a high number of multi-MeV deuterons from thick CD2 targets irradiated by intensity of 3× 1016 W cm−2. In the reported experiments fast fusion neutrons with energy up to 16 MeV were produced through 7Li(d, n)8Be and 11B(d, n)12C reactions in a pitcher-catcher target configuration. When using a large area CD2 foil as a secondary catcher target the total maximum neutron yield from the 2H(d, n)3He reaction increased by a factor of about 5, from 4× 108 to 2× 109. This result reveals that most of the deuterons having enough kinetic energy to enter a fusion reaction are emitted from the primary target into vacuum.
