The use of high reflectivity dielectric mirrors to form a high finesse optical cavity allows one to achieve long optical path lengths of up to several kilometres for high-sensitivity spectroscopy applications [1,2]. The high reflectivity of a dielectric mirror is achieved via constructive interference of the Fresnel reflection at the interfaces produced by multilayer coatings of alternate high and low refractive index materials [3]. This wavelength-dependent coating limits the bandwidth of the mirror's high reflectivity to only a few percent of the designed central wavelength.

We report on the recent development of a novel optical cavity based on prisms as cavity reflectors [4-6], which offers a high-finesse optical cavity operating in a broadband spectral region from 400 to more than 1600 nm [7] and provides a very suitable high-sensitivity spectroscopic technique for frequency-comb application.
