We discuss our design, construction, and characterization of thin-film Gires–Tournois interferometers for cubic-phase correction of ultrashort (<10-fsec) laser pulses. We include in the theory of the group delay of Gires–Tournois interferometers the dispersion of the thin-film layer, an important effect in the broadband limit. We characterize and use specific broadband, high-efficiency, low-dispersion substrates for this application.
