用于Z-pinch诊断的266nm激光探针分幅阴影成像系统
Framing shadowgraphy of 266nm laser probing for the diagnosis of Z-pinch plasmas
【摘要】 采用Nd-YAG激光器的四倍频激光(266nm)设计了激光探针分幅阴影成像系统,该系统具有时间分辨率和收光效率高,测量范围大,可有效屏蔽可见光干扰的优点,在钨丝阵实验中成功获得晚期内爆等离子体的分布图像.对系统结构和性能参数做了介绍,对测量结果进行了讨论.
【Abstract】 Framing shadowgraphy of UV laser probing with the 4th harmonic Nd-YAG Laser was developed for the diagnosis of Z-pinch plasmas.This system can effectively shield visible light and has advantages of high temporal resolution,large optical angular aperture and wide measuring range.The designed parameters and experimental results in implosions of tungsten wire array are presented in this paper.
