Wavefront aberrations play a major role when
focusing an ultrashort laser pulse to a high-quality focal
spot. Here, we report a novel method to measure and
correct wavefront aberrations of a 30-fs pulsed laser beam.
The method only requires a programmable liquid-crystal
spatial light modulator and a camera. Wavefront retrieval is
based on pupil segmentation with an annular lens array,
which allows us to determine the local phase that mini-
mizes focusing errors due to wavefront aberrations. Our
method provides accurate results even when implemented
with low dynamic range cameras and polychromatic
beams. Finally, the retrieved phase is added to a diffractive
lens codified onto the spatial light modulator to experi-
mentally demonstrate near-diffraction-limited femtosecond
beam focusing without refractive components. [-]
