Abstract
Characterizations of the vapor plume from a LY12 aluminum target irradiated by a focused normal mode pulsed Nd:glass laser beam have been studied by a plate shearing interferometer and high speed photography. The frame photos show that the speeds of the shock wave around the air are approximately treble that of the vapor plume front. At different sections (z), the refractive indexes are calculated with the Abel inversion, the electron density is about 7 X 1017 cm-3, the electron temperature is about 6,700 K by means of the saha equations.
