Abstract
A photograph of a white-light vortex obtained by means of volume phase holographic optical elements that allow creating achromatic vortices for a wide spectral range is shown. The elements have been recorded in dichromated gelatin and have a high damage threshold, so they are suitable for the generation of optical vortices with ultraintense femtosecond laser pulses.
