Optical resonator, carbon isotope analyzer using the same, and carbon isotope analysis method

摘要

Carbon dioxide isotope production from carbon isotopesThe step of filling the carbon dioxide isotope into an optical resonator having a pair of mirrors andIrradiation of irradiation light having an absorption wavelength with respect to said carbon dioxide isotopes in an optical cavityThe optical axis of the irradiation light and the optical axis of the light caused by the etalon effect do not matchAdjusting the relative positional relationship between the mirrorsThe step of measuring the intensity of the transmitted light obtained when the carbon dioxide isotopes irradiate and irradiate the irradiation light andCalculating the carbon isotope concentration from the intensity of the transmitted light andCarbon isotope analysis method.An optical resonator capable of suppressing the parasitic etalon effect, and a carbon isotope analysis apparatus and a carbon isotope analysis method using the same.
