Abstract: Cavity enhanced absorption spectroscopy systems and methods for detecting trace gases using a resonance optical cavity, which contains a gas mixture to be analyzed, and a laser coupled to the cavity by optical feedback. The cavity has any of a variety of configurations with two or more mirrors, including for example a linear cavity, a v-shaped cavity and a ring optical cavity. The cavity will have multiple cavity resonant modes, or a comb of frequencies spaced apart, as determined by the parameters of the cavity, including the length of the cavity, as is well known. Systems and methods herein also allow for optimization of the cavity modes excited during a scan and/or the repetition rate.

Abstract: A sensing apparatus for detecting light of first and second fluorescent wavelength bands has a light source to generate an excitation wavelength to a first collimator element. A dichroic multiplexer has a first coated surface oblique to the optical axis and treated to transmit the excitation wavelength and to reflect the second fluorescent wavelength band and a second coated surface treated to transmit the excitation wavelength and the second fluorescent wavelength band and to reflect the first fluorescent wavelength band. A focusing element focuses the excitation light toward a light guide and directs collimated light of the first and second fluorescent wavelength bands from the light guide to the dichroic multiplexer. A first detector element is in the path of reflected light of the first fluorescent wavelength band and a second detector element is in the path of reflected light of the second fluorescent wavelength band.

Abstract: In accordance with the present invention, an ultra-sensitive Raman chemical sensor is provided that is based on an enhanced spontaneous emission as a result of cavity quantum electrodynamic effects. More specifically, the sensor in accordance with the present invention makes use of a double resonance of a microcavity with both the excitation laser frequency and the Raman frequency. As such, the Raman shift corresponds to an integer times the free spectral range of the microcavity. Because the Raman frequency directly depends on the excitation laser's frequency, the fulfillment of the resonance condition for the excitation laser frequency guarantees that resonance with the Raman frequency is also satisfied.
