19. This critical dispersion criterion is equivalent to requiring the transverse spatial period of the phase modulation to be equal to the width of the lens aperture (for a square lens).
20. The dependence of the evolution of the intensity distribution on the number of phase plate elements was tested for the RPP case by doubling the lateral dimensions with the same spatial resolution. This increased the phase plate elements fourfold but the number in Fig. 4 was unchanged.
21. 2 is 4% for the PS case.
22. In an experiment, the plasma parameters, e.g., the temperature, at higher mean intensity might change as well and affect this conclusion.
