Abstract

We demonstrate the design, production, characterization and application of two dispersive complementary mirror pairs compensating second-and third-order dispersion, respec-tively. Both mirror pairs operate in the spectral range from 1.2-3.2 mu m. This is an unprecedented bandwidth of over 1.4 octaves which can drive further improvements in Cr:ZnS, Cr:ZnSe and other laser systems with a central wavelength around 2 mu m. The first pair provides a constant group delay dispersion of-100fs2, while the second one enables the compensation of the third-order dispersion that is introduced by a TiO2 crystal.(c) 2022 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
