Abstract. We present a technique called differential cavity ring-down spectroscopy (D-CRDS) for reducing etaloning effects in a ring-down spectrometer. The method relies on alternately measuring and then subtracting intra-cavity losses associated with pairwise TEM00 modes that are separated in frequency by an integer number of cavity free

Introduction Cavity ring down spectroscopy (CRDS) is a ver- satile high sensitivity absorption technique, exploited in an increasing number of investigations these last few years. Some of the published CRDS spectra correspond to absorption as small as 10-7 for one pass through the sample (a gas or a supersonic jet).

Thus the advantages include: High sensitivity due to the multipass nature (i.e. long pathlength) of the detection cell. Immunity to shot variations in laser intensity due to the measurement of a
