<正>This paper reports the experimental results on the investigation of laser heating andcompression of microspherical targets using our six-beam glass laser system.Irradiationexperiments were generally performed with two of the six-beams.laser power in each beamwas typically 100 gigawatts and the pulse width 100 picoseconds.Two kinds of targetswere used:(CD2)_n solid microspheres(—60 to 600μm in diameter) and glass microbal-loons(—55 to 75μm in diameter with—0.55 to 0.75μm thick walls)filled with neonor deuterium gas.In our experiments,various parameters of laser plasmas could besimultaneously measured by more than ten kinds of diagnostics for optical measurments,X-ray and particle emission studies.Preliminary physical results of target compressionand laser nonlinear interaction with target corona have been presented.
