首次报道了用受激布里渊散射位相共轭反射镜作为直接驱动惯性聚变能量(IFE)替代方案的实验结果。将高次谐波转换晶体直接包含在激光轨迹中，结合色散楔形物，证实了激光驱动器在注射弹丸表面实现全自动自动导航的可能性。基于预期的大量单个激光驱动器，提出了一种以适当定制(在能量和延迟方面)相邻光束的组合的形式来实现IFE方案所需的最终辐照脉冲时间分布的方法。提出了一种能量约为1kJ的小球激光驱动通道的概念设计，并进行了数值计算，为实际设计中需要考虑的重要问题提供了指导。
The very first results obtained in experiments especially designed for verification of the stimulated Brillouin scattering phase conjugating mirror-based inertial fusion energy (IFE) approach as an alternative to the standard direct drive IFE scheme are reported. Inclusion of a higher harmonic conversion crystal directly into the laser beam trajectory, in combination with a dispersive wedge, confirmed the possibility of fully automatic self-navigation of laser drivers on the surface of injected pellets. Based on the expected very large numbers of individual laser drivers, a method for the realization of the final irradiation pulse temporal profile required by the IFE scheme was proposed in the form of a combination of suitably tailored (in energies and delays) neighboring beams. The conceptual design of one laser driver channel for an energy of pellet irradiation of similar to 1 kJ was proposed and numerically evaluated, providing guidance for the most important issues to be taken into consideration in practical designs.
