Coherent X-ray mirage: discovery and possible applications
Fig. 1. (a) Scheme of the experiment. (b) Typical image of an XRL far-field intensity distribution, obtained in one shot.
Fig. 2. Experimental observation of the interference pattern in the intensity distribution of the output of an oscillator–amplifier XRL beam after 30 accumulated shots.
Fig. 3. Optical scheme of fringe formation by two point coherent sources.
Fig. 4. Comparisons of experimental and modeled interference patterns for the case of the distance between two phase-matched X-ray point sources being 203 mm.
Fig. 5. Schematic explanation of the theoretical algorithm for X-ray mirage formation. (a) XRL radiation from the generator (seeded beam) propagated in empty space with complex amplitude ; (b) after propagation of the seeded beam through plasma of the amplifier, the complex amplitude of the distorted radiation consists of two terms: the complex amplitude and the complex amplitude of the mirage ; (c) formation of imaginary source by running the complex amplitude backward in empty space.
