  • Spectroscopy system using waveguide and employing a laser medium as its own emissions detector
    Patent number: 9851248
    Abstract: An intracavity laser absorption infrared spectroscopy system for detecting trace analytes in vapor samples. The system uses a spectrometer in communications with control electronics, wherein the control electronics contain an analyte database that contains absorption profiles for each analyte the system is used to detect. The system can not only detect the presence of specific analytes, but identify them as well. The spectrometer uses a hollow cavity waveguide that creates a continuous loop inside of the device, thus creating a large path length and eliminating the need to mechanically adjust the path length to achieve a high Q-factor. In a preferred embodiment, the laser source may serve as the detector, thus eliminating the need for a separate detector.
