These mirrors are manufactured with a silver coating and dielectric overcoat, a combination which provides >98.5% reflectance for p-polarized light and >99% reflectance for s-polarized light over the 750 - 1000 nm wavelength range at 45° AOI. Our -AG coating largely retains the low group delay dispersion (GDD) intrinsic to metallic coatings with the |GDD| for s-polarized light < 20 fs2 and the |GDD| for p-polarized light < 30 fs2.
The plot to the right shows the measured reflectance of this coating as a function of wavelength. The shaded region denotes the range over which we recommend using these optics. Data was obtained at a 45° angle of incidence.
