A beam shaper suitable for sub-20 fs pulses based on a prism pair and a computer-generated hologram was developed to produce vortex beams. Comparatively high throughput and the ability to tune the group-velocity dispersion make this shaper suitable for pulses from femtosecond oscillators and amplifiers and where there is a need for additional postchirp or prechirp compensation.
