Differential cavity mode spectroscopy: A new cavity enhanced technique for the detection of weak transitions

De Vine, Glenn; McClelland, David; Gray, Malcolm


We present a new cavity enhanced, continuous wave spectroscopic technique for the detection of weak atomic and molecular transitions. Differential Cavity Mode Spectroscopy (DCMS) measures the difference in absorption between two adjacent cavity longitudinal modes to yield a highly sensitive, yet relatively simple, cavity enhanced spectroscopic technique. In addition this relative absorption measurement is, to first order, independent of both laser frequency noise and cavity acoustic noise. Here...[Show more]
