New Complementary pair of dispersive multilayers

November 25, 2019

featured publications – The AMO group as a part of the Laboratory for Attosecond Physics has for the first time designed and produced Complementary pair of dispersive multilayers operating in the 2-4 µm spectral range. The mirrors comprise layers of Si and SiO2 thin-film materials. The pair exhibits unparalleled reflectance exceeding 99.7% and provides a group delay dispersion of (-200) fs2. The mirrors can be used in Cr:ZnS/Cr:ZnSe femtosecond lasers and amplifiers.
