Simulation parameters are: the central distance between grating and sample is 10 mm (zero value in the figure); grating period D = 200 nm; phase depth of grating is 0.5 π for wavelength 0.248 nm (5 keV) and 0.3π for 0.171 nm (7.24 keV); beam waist value is w = 97 μm; phase effectivity parameter β = 0.1; and pump to probe intensity ratio is p = 1.
