Accounting for the detection response brings cavity ring-down spectroscopy to sub-permille accuracy

Rajesh Chell, Marcin Gibas, Szymon Wójtewicz +3

For nearly four decades, cavity ring-down spectroscopy (CRDS) has been among the simplest, most widely used absorption techniques, requiring no calibration because it measures deca…
