论文摘要
Deuteron-Triton（DT）融合是受控融合研究中使用的主要融合反应，与其他融合选项相比，主要是因为其相对较高的反应横截面。即便如此，为了达到可观的反应概率，需要很高的温度（按100-1亿开尔文尔（Kelvins）），这是实现和维持的极具挑战性的。我们表明，强烈的低频激光场，例如全球大多数激光设施的近红外政权中的强度，在将能量转移到DT系统并增强DT融合概率方面非常有效。融合概率至少在800 nm激光场中的数量级显示，其强度为10 $^{21} $ w/cm $^2 $。如果利用强烈的低频激光器，则可以放松受控核融合的苛刻温度需求。
Deuteron-triton (DT) fusion is the primary fusion reaction used in controlled fusion research, mainly for its relatively high reaction cross sections compared to other fusion options. Even so, to attain appreciable reaction probabilities very high temperatures (on the order of 10-100 million kelvins) are required, which are extremely challenging to achieve and maintain. We show that intense low-frequency laser fields, such as those in the near-infrared regime for the majority of intense laser facilities around the world, are highly effective in transferring energy to the DT system and enhancing the DT fusion probabilities. The fusion probabilities are shown to be enhanced by at least an order of magnitude in 800-nm laser fields with intensities on the order of 10$^{21}$ W/cm$^2$. The demanding temperature requirement of controlled nuclear fusion may be relaxed if intense low-frequency lasers are exploited.
