DEVICE FOR QUANTITATIVELY DETECTING CARBON-14 ISOTOPE USING DOUBLE-WAVELENGTH METHOD, AND SPECTROMETER

A device and a spectrometer for quantitatively detecting carbon 14 isotope by a dual-wavelength method. Two mid-infrared lasers with different wavelengths are locked in an optical cavity of a sample chamber (15), to ensure the two lasers are collinear. The cavity length of the optical cavity is adju...
