Abstract
A dielectric mirror is provided that, on the one hand exhibits a high destruction threshold when being irradiated with ultrashort high-power laser pulses, and on the other hand has a large bandwidth of group delay dispersion. The dielectric mirror includes a layer stack with a sequence of layers having different refractive indices, which act as a reflecting interference filter, wherein the layers are formed of at least three different materials exhibiting different destruction thresholds.
