O p t i c s 617 Email: sales@newport.com • Web: newport.com WINDOWS BEAMSPLITTERS OPTICAL FILTERS POLARIZATION OPTICS DIFFRACTION GRATINGS HIGH-ENERGY OPTICS ULTRAFAST LASER OPTICS ACCESSORIES • For precise dispersion compensation • For external cavity pulse manipulation • UV fused silica, LaKL21 optical glass or NEW SF10 higher index material • 15 mm or 25 mm sizes Ultrafast Laser Brewster’s Angle Dispersing Prisms These prisms are used intracavity to compensate for dispersion of fixed cavity optics, such as a Ti:Sapphire crystal, or external cavity to manipulate pulse characteristics. Three prism materials (fused silica, SF10 and LaKL21) are offered to compensate for different pulse dispersion conditions. Two sizes are available in each material: 25 mm and 15 mm.
