Saint-Gobain Crystals has unveiled two laser beam delivery mirrors. The Alpine Research Optics brand B-Max mirrors support Ti:sapphire lasers with pulse widths of ≤10 fs and deliver >99.8% reflectivity from 735 to 880 nm. The E-Max models operate from 770 to 840 nm. Both series’ coatings are designed to minimize group-velocity and third-order dispersion to maintain close to a transform-limited pulse performance in ultrafast laser systems. The coatings are available for 0° and 45° angle of incidence operation and are supplied on 25- and 50-mm-diameter fused-silica substrates.
