为了实现高重复惯性约束聚变（ICF）实验，研制了一种由二极管泵浦固体激光器（DPSSL）泵浦的Ti：蓝宝石激光器HAMA。为了演示反辐照快速加热聚变方案，将3.8 J， 0.4 ns的放大啁啾脉冲分成四束：两束以6 × 10(13) W cm（-2）的强度反照射目标，其余两束脉冲压缩到110 fs，以2 × 10(17) W cm（-2）的强度加热内爆目标。HAMA为首次演示做出了贡献，证明了10 J级DPSSL适用于ICF实验，并成功地在重复模式下产生了DD中子。在此基础上，我们设计并开发了包含目标注入和跟踪的集成重复ICF实验机。
A Ti: sapphire laser HAMA pumped by a diode-pumped solid-state laser (DPSSL) is developed to enable a high-repetitive inertial confinement fusion (ICF) experiment to be conducted. To demonstrate a counter-irradiation fast-heating fusion scheme, a 3.8 J, 0.4 ns amplified chirped pulse is divided into four beams: two counter-irradiate a target with intensities of 6 x 10(13) W cm(-2), and the remaining two are pulse-compressed to 110 fs for heating the imploded target with intensities of 2 x 10(17) W cm(-2). HAMA contributed to the first demonstration by showing that a 10 J class DPSSL is adaptable to ICF experiments and succeeded in DD neutron generation in the repetition mode. Based on HAMA, we can design and develop an integrated repetitive ICF experiment machine by including target injection and tracking.
