Abstract: A system. The system includes a first beam path configured to transmit a first light beam having a first optical wavelength and a second beam path configured to transmit a second light beam having a second optical wavelength distinct from the first optical wavelength. A first beam splitter disposed at an intersection of the first beam path and the second beam path. The first beam splitter is configured to superimpose the first and second light beams to form a third light beam, the third light beam impinging on a first window of a sample cell. The sample cell defines an interior volume and is configured to transfer the third light beam from the first window to a second window along a light path within the interior volume. The light path comprises a plurality of segments. The third light beam undergoes at least one reflection at an end of each segment, wherein the light path passes through a gas sample disposed within the interior volume.
