Abstract
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, to ensure the two lasers are collinear. The cavity length of the optical cavity is adjusted by a cavity length adjusting unit, to tune the mode frequency of the optical cavity, and then tune the frequencies of the two mid-infrared lasers, so that the frequencies of the two mid-infrared lasers match with different energy levels of the target isotope molecule simultaneously. After the frequencies of the mid-infrared lasers match with the energy levels of the target isotope molecule simultaneously, the target isotope molecule is excited by two mid-infrared lasers simultaneously, and the optical cavity output signal of the second mid-infrared laser passing through the optical cavity is detected.
