We have made a prototype based on CRDS with 2 {mu}m diode laser for carbon isotope analysis of CO{sub 2} in air. The carbon isotope ratio was obtained to be (1.085{+-}0.012)x10{sup -2} which shows good agreement with the isotope ratio measured by the magnetic sector-type mass spectrometer within uncertainty. Hence, we demonstrated the carbon isotope analysis based on CRDS with 2 {mu}m tunable diode laser.
