Title: Research on space-time evolving feature of laser-induced Ni plasma′s electron temperature and electron density
Abstract: Laser-induced Ni plasma′s electron temperature and electron density have been calculated through the determination of atomic line′s relative intensity,as well as the broadening and line-shifting of Stark.The relationship between time delay,spatial location and the two important parameters,i.e.electron temperature and electron density have been studied through the changing of the delayed time between spectrum signal and laser pulse,as well as the changing of shifting imaging lens′ location.The results show that the electron temperature and the electron density correlate closely with the time delay and the spatial location.In time resolution,the plasma′s electron temperature and electron density decrease exponentially with the delay time.In space resolution,the electron temperature and the electron density observe Lorentz rule with the distance from the targeting point.
