515, 1030nm, 12.7mm Dia., Dual Band Low GDD Mirror

Product Details High Reflectivity & Low Group Delay Dispersion (GDD) for Ultrafast Beam Steering Ion-Beam Sputtered (IBS) Coatings Minimize Scatter and Absorption Losses Near-Zero GDD for Both the First and Second Harmonics of Ti:sapphire and Yb-doped Lasers TECHSPEC Dual Band Low GDD Ultrafast Mirrors maintain high reflectivity and near-zero group delay dispersion over both the first and second harmonic of Ti:sapphire and Yb-doped lasers. Utilizing Ion-Beam Sputtered Coating Technology, these mirrors minimize scatter and absorption loss commonly observed when using other traditional coating application processes. TECHSPEC Dual Band Low GDD Ultrafast Mirrors are often used in beam steering applications as they will maintain ultrashort pulse durations that can be difficult to preserve when using more conventional laser mirrors. These mirrors are ideal for second-harmonic generation (SHG) microscopy and spectroscopy applications as well as for frequency resolved optical gating (FROG).
