Abstract
  • continuous wave quantum cascade laser (QCL), operating near 8.1 mum, was used for wavelength modulation spectroscopy of methane (CH4) and nitrous oxide (N2O) stable isotopes. Several rotational transitions of (N2O)-N-14-O-16, (NNO)-N-15-N-14-O-16, (N2O)-N-14-O-18, (N2O)-N-14-O-17, (CH4)-C-13 and (CH4)-C-12 fundamental bands were detected. The noise-equivalent absorbance was measured to be less than 10(-5) in a 1-Hz bandwidth. A characterization of the laser source was also performed. The use of a QCL spectrometer for high-precision isotope ratio measurements is discussed. (literal)
