Abstract
Two-dimensional (2D) radiation hydrodynamics simulations have been performed to investigate the refraction influence and the gain property in the plasma medium of the x-ray laser. The local energy deposition of the main pumping pulse generates a blast wave near the critical density surface, and the density dip structure is gradually formed behind the blast wave. The three-dimensional (3D) ray-trace calculation using the result of the 2D simulation shows the x-rays pass through the density dip with less refraction.
