Abstract
The invention relates to dispersion adjustment units for electromagnetic radiation having a spectral width, e.g., for laser pulses. The dispersion adjustment unit includes at least one dispersive element for producing angular dispersion in an angular dispersion region limited by two interaction regions of the electromagnetic radiation with the at least one dispersive element. In the angular dispersion region, individual spectral components of the electromagnetic radiation are associated with optical paths extending at an angle to one another. Furthermore, the dispersion adjustment unit includes an optical unit that is arranged in the angular dispersion region and includes an optical element that transmits the electromagnetic radiation. The optical element effects an incidence-angle-dependent parallel offset of the individual spectral components of the electromagnetic radiation with respect to the propagation of the individual spectral components before and after the optical unit.
