The spectral and spatiotemporal properties of Bessel-Gauss pulsed beams focused by a dispersive aperture lens are studied, where the dispersion of the first, second, and higher orders is taken into consideration. It is shown that the spectral switches take place at the geometrical focal plane, and t
