Abstract

We report the design and operation of novel super-high reflectivity negative dispersion dielectric mirrors for use in tunable ultrafast laser systems. The mirror structure is divided into two distinct regions: an underlying super-high reflectivity dielectric quater wavelength stack, and an overlying negative dispersion section consisting of only a few layers and forming simple multiple Gires-Tournois Interferometers. The mirror structure presented in this paper was designed for operation from 800-900 nm and has a near constant group dispersion delay of -40 fs2 and a peak reflectivity greater than 99.99%. We show a comparison of the predicted and measured mirror performance and their application in a modelocked ti:sapphire laser tunable from 805-915 nm.
