OPTOMAN’s IBS-coated Chirped Mirrors are designed to provide precise negative Group Delay Dispersion (GDD), making them essential for compensating pulse broadening in ultrafast laser systems. These mirrors feature multilayer dielectric coatings with wavelength-dependent optical thicknesses that introduce controlled delay, enabling compact and alignment-insensitive pulse compression without the need for prisms or gratings.
Optimized for Yb:YAG II harmonic operation at 515 nm and a 45° angle of incidence, this chirped mirror offers a high reflectivity and a precise dispersion control with GDD value at -200 fs^2.
