Improved broadband Double-Chirped Mirrors with controlled dispersion characteristics

Abstract

We present a theory for the analytical design of double-chirped mirrors (DCMs) with a controlled dispersion characteristic. Theoretical designs are derived from an analytical chirp law. These are then used as excellent starting designs for later computer refinement. The design procedure presented here results in improved broadband DCM designs for higher order dispersion compensation in sub-10-fs Ti:sapphire lasers.
