Abstract
Provided is a carbon isotope analysis device including a carbon dioxide isotope generator provided with a combustion unit that generates gas containing carbon dioxide isotope from carbon isotope, and a carbon dioxide isotope purifying unit; a spectrometer including optical resonators having a pair of mirrors, and a photodetector that determines intensity of light transmitted from the optical resonators; and a light generator including a single light source, a first optical fiber that transmits first light from the light source, a second optical fiber that generates second light of a longer wavelength than the first light, the second optical fiber splitting from the first optical fiber and coupling therewith downstream, a first amplifier on the first optical fiber, a second amplifier on the second optical fiber, different in band from the first amplifier, and a nonlinear optical crystal.
