Abstract

Picosecond microscopic photography with high spatial-and temporal-resolutions was applied to the investigation of laser-produced plasmas. An interferometer with resolutions of 2 µm and 20 psec was developed for measuring plasma density. Shock waves propagating inside targets and plasma density profile were observed. It is pointed out that spatial nonuniformity of the laser light produces nonuniform acceleration in the hydrodynamic motion. Density profile indicates strong steepening pushed by intense radiation pressure.
