Abstract

A high finesse cavity operating around 620 GHz has been constructed to improve the sensitivity limit for the measurement of weakly absorbing gases. An effective path length of 1 km is achieved significantly improving the available sensitivity. The measurement of the cavity decay time allows the quantification of the absorption coefficient.
