摘    要: 主要介绍为了满足神光-Ⅱ高功率激光装置三倍频光(351nm,3ω)的物理实验要求,靶场三倍频模拟光源和瞄准监视系统两个主要单元技术的改进,即三倍频模拟光源由基频光(1 053nm,3ω)通过腔外的KTP+BBO晶体倍频获得,再经八路分光系统和主激光耦合;瞄准监视系统由透射式光学系统改进为反射式光学系统,避免原系统存在较大的色差,提高瞄准精度。

关 键 词:靶场单元技术  三倍频  模拟光  瞄准监视系统

Abstract:The paper concerns the improvement of two primary technologies for 3ω(351nm) shot experiment in SG-Ⅱ facility target area ,which are 3ω target alignment laser and optical viewing system .The 1ω (1 053nm) laser is exported form the Nd:YLF laser and passes the KTP+BBO system to acquire the 3ω laser.And the 3ω laser is coupling-out with main laser.In order to improve the laser accurately position on the target,the reflection optical system is replaced by the transmission optical system,which avoids the effect of chromatic aberration.
Keywords:Primary technology of target area  Third harmonic beam  Target alignment laser  Optical viewing system
