| 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. |
