Beam-spot profiles captured 2 cm before the geometrical focus inside the filaments with different aperture sizes (a) without and (b) with the phase plate. Aperture sizes and the corresponding pulse energies after the aperture are given in each frame. For more, see the paper by Fu et al., pp. 3752-3754.
