【摘要】 光路自动准直系统应用于惯性约束聚变的高功率激光装置中。针对神光Ⅱ第九路装置,设计了一套可行的准直方案,并在装置上进行了实验。实验结果表明,自动准直系统能够在15min内顺利完成光路的自动调整,小口径近场调整准直精度小于±0.5mm,大口径近场调整准直精度小于±1.0mm,远场准直精度小于±1″,满足了装置的设计要求。更多还原

【Abstract】 The laser beams automatic alignment system is used in the high power laser facility for inertial confinement fusion.Considering the ninth beam of SG-Ⅱ,a reasonable scheme for automatic alignment is presented.It has been demonstrated on the experiment system.Results indicate that beam paths adjustment can be finished in 15mby the automatic alignment system.The precision of the small-caliber near-field adjustment is less than±0.5mm and the large-caliber nearfield adjustment is less than±1.0mm.The accuracy of the far-field adjustment is less than±1″.Requirements of the facility are met.更多还原
