摘要： A gas detection system includes a light detector, a pump laser with spectral emission between UV and IR wavelengths and structured to generate a laser beam, a hollow waveguide structured to receive a sample gas, the hollow waveguide having a bandwidth sufficient to transmit the laser beam and Stokes Raman photons scattered by the sample gas, and an optical system. The optical system is structured to: (i) direct the laser beam into the hollow waveguide such that it propagates in the hollow waveguide in one or more low-order low-loss waveguide modes, and (ii) direct Raman signals generated within the hollow waveguide in response to the laser beam interacting with the sample gas toward the light detector, the Raman signal including the Stokes Raman photons.
