We propose that the bending profile of a mechanical deformable mirror can be designed by shaping its form, realizing a simple, compact, and broadband group delay dispersion compensator in a 4-f pulse shaper arrangement. By using the proposed compensator, spectral phase distortion of a microscope objective lens is successfully pre-compensated for to generate a sub-8 fs pulse at the focus of the lens.
