We present an analytical technique based on direct absorption laser spectroscopy for high precision and simultaneous determination of the mixing ratios of the most abundant nitrous oxide isotopic species: 14N15N16O, 15N14N16O and 14N216O. A precision of 0.5‰ was achieved for the site specific isotope ratios of N2O at 90 ppm using an averaging time of 300 s.
