    LARGE OPTICS: Petawatt high-LIDT coatings don't sacrifice performance

    Nov. 1, 2012
    High laser-induced damage threshold (LIDT) optical coatings help enable the highest-peak-power lasers in existence today.
    FIGURE 1. A mirror designed for use inside a laser cavity has R >99.95% over a bandwidth of 500 nm (a). A mirror for cavity ring-down spectroscopy (CRDS) has R = 99.9994% at 1650 nm (b).

    OPTICS FABRICATION: High-performance mirrors excel for intracavity applications

    Neil Anderson
    Feb. 1, 2012
    With carefully controlled absorption and scattering losses, high-reflectivity, low-loss dielectric mirrors enable demanding applications such as gravitational-wave detection and...
    FIGURE 1: Absorption (green shaded area) and emission (pink shaded area) spectra of the three fluorophores used in the research describe fluorescence image-guided tumors and surrounding tissue. The spectra of optimal corresponding filters (green line) can be used in a FIGS microscope. Hard-coated interference filters having high (>95%) light transmission passbands and steep edges enable the collection and display of fluorescence microscopy images with high signal-to-noise ratios (for example, high image fidelity). So, high-quality optical filters are critical for removing small pieces of tumor that may otherwise go undetected.
