    Ultralow-Loss Mirrors Boost Spectroscopy, Detection Capabilities

    Article obtained from BioPhotonics RSS Feed.

    Collaborators from industry and academia have demonstrated high-performance laser mirrors in the mid-infrared range that absorb fewer than 10 out of a million photons. The achievement, enabled by recent advancements in optical coating technology, has the potential open applications in medicine and environmental monitoring.

    The coating process involves the deposition of single-crystal stacks of high-purity semiconductor materials via an epitaxial growth process. The monocrystalline multilayers that are produced are then transferred onto curved silicon optical substrates by a proprietary bonding process. The completed mirrors were tested at both the Christian Doppler Laboratory (CDL) and NIST.

    “This new process enables…
