强激光场中氘团簇双重膨胀引发核聚变

Nuclear Fusion Induced by Dual Explosion of Deuterium Cluster in Strong Laser Field

在超强fs激光与氘团簇的相互作用中 ,分析了可以引发核聚变的高能氘核产生的原因 ,提出了团簇双重膨胀的机制 ,计算了氘核动能及团簇解体的时间 ,为选取合适的激光脉冲宽度参数提供参考 .

Considering the Coulomb explosion induced by the interaction of a deuterium cluster target with ultra-intensity femtosecond laser, the causation which generate energetic deuterium nuclei for the fusion has been analyzed. The mechanism for the dual explosion of deuterium cluster is proposed, and hence the velocity of deuterium nuclei and the expansion time of deuterium ion clusters have been estimated.
