We analyze the spatiotemporal intensity of Gaussian temporal envelope pulses with initial durations of and a carrier wavelength of at the paraxial focal plane of an achromatic doublet lens for a well-collimated incoming pulse beam by using the Seidel aberration theory for thin lenses with the stop at the lens. We analyze the effect of these aberrations in the focusing of ultrashort pulses for Gaussian illumination and present experimental results for pulses focused by a near-IR achromatic doublet.
