Experimental founding of unknown interference structure in a spatial profile of the output beam of the two-stage plasma X-ray laser is reported. It is allowed us experimentally and theoretically discovers a new phenomenon - generation a phase-matched coherent point source of soft X-ray radiation in a plasma media by propagated X-ray laser seeded beam, which could additionally extend the applications of such lasers. We have developed a method of solving the Maxwell-Bloch equations, which has gave us finding that the observed phenomenon is due to the emergence in the plasma-amplifier of X-ray mirage in the form of the phase-matched coherent virtual point source.
