The conversion of laser light into soft X-rays during interaction of intense laser light with a planar gold target is investigated numerically with the help of the MULTI code. It solves one-dimensional hydrodynamics including flux-limited electron heat conduction, multigroup radiation diffusion, and steady-state non-local thermodynamic equilibrium radiation physics. The influence of various parameters such as the laser intensity, wavelength, and pulse duration on the conversion efficiency of laser light into X-rays is studied. Particular emphasis is placed on comparing the numerical results with the model presented in Part I. According to this model the radiating plasma can be divided into a conversion layer and a reemission zone. Its essential features are confirmed by the numerical results.
