Modeling of Ni-like Molybdenum x-ray laser by ray tracing algorithm

Ni-like Molybdenum plasma is modeled with atomic physics and hydrodynamic code EHYBRID. In the model the Molybdenum slab target is pumped with double pulse and 1054 mu Nd:Glass laser is used as the pumping laser. The most efficient plasma condition obtained with the configuration of a main pulse with 1.2 ps duration and 3.5 x 10(14) Wcm(-2) intensity pumped peak to peak 340 ps after a pre-pulse with the duration of 280 ps and intensity of 1.2 x 10(12) Wcm(-2) is concerned for the ray-tracing. The radial and transverse refraction of x-ray laser propagating along longitudinal axis of the plasma is calculated with the refraction equation numerically by Runge-Kutta method. The amplification of 18.9 mn Ni-like Molybdenum x-ray laser along its path through the plasma is modeled and the near-field image of the intensity at the exit of the plasma is obtained.
