Abstract
The thermodynamic state of a high-temperature laser-induced emitting plasma has been studied based on numerical simulation data. Laser-induced X-ray radiation characteristics versus wavelength and intensity of an incident Nd-laser pulse have been discussed for those ranges of these parameters where the condition for compression of an inertial-confinement fusion target by an X-ray pulse is met. Another object of investigation was the thermodynamic state of a plasma produced by a laser-induced X-ray radiation pulse acting on plane targets made of light materials that are most in demand as materials for a target outer layer (so-called ablator), within which a target-compressing pressure is developed. The thermodynamic characteristics of the plasma produced by the laser pulse have been compared with those of the plasma produced by the pulse of laser-induced X-ray radiation.
