Abstract

Broadband cavity enhanced absorption spectroscopy can be used to perform detection of gases with a very high sensitivity due to the very long optical path of the cavity [1]. Compared to coherent methods, cavity enhanced absorption spectroscopy is simpler and more robust allowing to readily perform in-situ measurements. Supercontinuum sources on the other hand possess unique properties in terms of brightness and spatial coherence that make them particularly suitable for a wide range of applications ranging from spectroscopy to imaging and chemical sensing [2].
