The two-dimensional Maxwell-Bloch code COLAX has been used to optimize the geometrical parameters of the half-cavity in a neon-like Zn X-ray laser. The tuning of the mirror position and curvature is shown to be a crucial step in designing such an experimental setup, as it influences both the amplified intensity and the spatial coherence of the double-pass X-ray laser beam.
