Reflection zone plates (RZP) and 2-dimensional variable line spacing (VLS) gratings are serving as a combination of three functions in one optical element (reflection, energy dispersion and focusing). They were used for the development of different types of spectrometers and monochromators with femtosecond time resolution in the soft x-ray energy range. In this paper, we also suggest to combine two identical RZPs placed in opposite orders of diffraction (+1 and -1) for compensation of time elongation of fs soft X-ray pulses down to several fs.
