For dielectric mirrors, materials with a refractive index between approx. 1.5 and 2.2 are available. The amplitude of the Fresnel reflection is about 0.2. With 10 layers about 0.99 of the light amplitude (that is, 0.98 of the light intensity) is reflected. So if a given chirped mirror has 60 layers, light of a specific frequency interacts only with one sixth of the whole stack. Reflection from the first surface amounts to an early reflection with unaltered chirp. This is preve… WebTheory of Double-Chirped Mirrors Nicolai Matuschek, Franz X.
