摘要
Line-focused high power laser was used to irradiate a magnesium slab target in order to generate line-shaped laser-plasma.Plasma parameter profile distribution(electron temperature and electron density)on the direction perpendicular to the target surface was obtained by spectroscopic diagnostic method,which is quite different from that of the spot-shaped laser-plasmas.New experimental phenomena that can be interpreted as“plasma satellites”were also observed.
