摘要

摘要: 惯性约束聚变（ICF）中的瑞利-泰勒不稳定性（RTI）研究需要基于多种结构的调制靶，针对目前调制靶制备的工艺问题，采用双光子3D打印工艺制备了平面调制、平面复合调制及球壳型调制三种典型结构的调制靶，靶材料为光敏树脂（95%：C₂₃H₃₈N₂O₈，5%：C₄H₆O₂）。采用激光共聚焦显微成像分析了三种调制靶的实际结构参数，三种靶型的实测形貌及其参数与设计结构及参数具有良好匹配度。为进一步验证双光子3D打印新型工艺制备调制靶的可行性，实验团队在“神光Ⅱ”高功率激光实验装置上进行了纳秒激光打靶实验，结果显示靶表面的调制在激光直接驱动下受RTI的作用随时间呈增长趋势，初始峰谷值为4 μm的调制在激光驱动2.5 ns后形成了长度达100 μm的高密度射流，表明基于高精度3D打印工艺制备结构复杂的调制靶用于RTI研究具有较高可行性。

Abstract: Rayleigh-Taylor instability (RTI) research in inertial confinement fusion (ICF) is based on modulation targets with multiple structures. In this paper, aiming at the present problems existing in the preparation of modulation targets, three typical modulation targets of planar modulation, planar composite modulation and spherical shell modulation have been prepared by two-photon 3D printing process. The target material is photosensitive resin (95%: C₂₃H₃₈N₂O₈, 5%: C₄H₆O₂). The actual structural parameters of the three modulation targets were analyzed using laser confocal microscopy imaging. The measured morphologies and parameters of the three targets show good matching with the designed structures. To further validate the feasibility of using new two-photon 3D printing process for preparing modulation targets, nanosecond laser targeting experiments were conducted on the “Shenguang II” high-power laser experimental facility. The results show that the modulation of the target surface increased with time due to the action of RTI under direct laser driving. The modulation with an initial peak valley value of 4 μm formed a high-density jet with a length of up to 100 μm after 2.5 ns of laser driving, which indicates that the preparation of complex modulation targets based on high-precision 3D printing technology is highly feasible for RTI research.
