Dispersive mirror for the mid-infrared spectral range of 9-11.5  μm.
A dispersive multilayer interference mirror with a group delay dispersion (GDD) of +1500  fs2for the spectral range of 9-11.5 μm is presented. It is designed to compensate the GDD of an ultrashort light pulse gained when transmitting 1 mm of a zinc selenide substrate. The coating process for the mirror manufacturing is described. The optical properties of the mirror are fully characterized by measuring the group delay, the GDD, the reflectance, and the transmittance.
