Abstract:
Systems and methods for detecting trace gases utilize a resonance optical cavity and one, two or more coherent light sources coupled to the cavity through one or more cavity coupling mirrors, whereby two or more optical cavities may share the same gas volume.

Claim (Index 3):
A system for detecting two or more analyte species present in a gaseous or liquid medium, the system comprising:\n a resonant optical cavity containing said medium and having at least two cavity mirrors, one of which is a cavity coupling mirror, the cavity having a plurality of optical resonance cavity modes; a first laser that emits continuous wave laser light, wherein the first laser is capable of being scanned whereby a mean optical frequency of the first laser is adjustable over a range of frequencies, and wherein the first laser is responsive to optical feedback light emerging from the cavity; mode matching optics configured to couple the first laser light to the cavity via the cavity coupling mirror at an angle non perpendicular to the mirror reflective surface; a second laser that emits continuous wave laser light, wherein the second laser is capable of being scanned whereby a mean optical frequency of the second laser is adjustable over a range of frequencies, and wherein the second laser is responsive to optical feedback light emerging from the cavity; mode matching optics configured to couple the second laser light to the cavity via the cavity coupling mirror making the laser beam from the first laser impinging on the mirror and the laser beam from the second laser impinging on the mirror non-collinear; and at least one detector configured to measure an intensity of the intra-cavity optical power of light circulating in the cavity and to generate a signal representing the intra-cavity optical power of light circulating in the cavity wherein the transmissivity of at least one of the cavity mirrors is selected such that the intensities of the optical feedback light impinging on the first and second lasers are below threshold intensity values so as to ensure that frequency hold interval ranges of the optical frequency of the first and second lasers are smaller than a free spectral range of the cavity.
