摘要

Nowadays, dispersive mirrors are able to cover the wavelength range of 4.5 optical octaves and can be used from 220 nm up to 4500 nm. Various design approaches to dispersive mirrors in visible and near IR are briefly discussed. We consider in more detail two dispersive mirrors representing extreme cases. The first one is a mirror working in the range of 290-360 nm and providing group delay dispersion of -75 fs~2. The second one is a mirror working in the range of 2500-4500 nm and providing +500 fs2 of group delay dispersion.
