Abstract
Spectroscopy systems and methods of comb-based spectroscopy are provided. A light source generates light corresponding to a frequency comb. A prism cavity is optically coupled to the light source. The prism cavity receives the generated light and produces first and second output light. The first output light is associated with reflection of the received light within the prism cavity. The second output light is associated with transmission of the received light through a prism of the prism cavity. A coupling system is coupled to the light source and the prism cavity. The coupling system adjusts a characteristic of at least one of the light source or the prism cavity, based on at least one of the first output light and the second output light. The characteristic is adjusted to increase optical coupling between the light source and the prism cavity and to compensate for a dispersion of the prism cavity.
