Crds spectroscopy
WebThat is where cavity ring down spectroscopy comes in: a precise method of verifying the exact reflectivity of the highest reflectivity mirrors. Cavity ring down spectroscopy (CRDS) works by means of a laser pulse, beamed into a resonant cavity that is bounded by two of the highly reflective mirrors being tested. WebCavity Ring Down Spectroscopy (CRDS) CRDS is a sensitive and absolute technique based on absorption spectroscopy. CRDS is frequently applied to the measurement …
