Nowadays, the concentration of greenhouse gases such as methane (CH 4 ) or carbon dioxide (CO 2 ) in the atmosphere greatly increased. For ecological purposes, it is relevant to discriminate different sources of CH 4 and CO 2 emissions (e.g., antropo

We introduce a Raman scattering based detector of carbon isotopes in gaseous mixtures. A solid state 532 nm 5 W CW laser focused into a gaseoussample by a custom-built diffraction-limited objective was used for excitation of Raman signal. Raman signa
Optical isotope ratio spectroscopy (OIRS) has recently gained popularity and maturity in isotope research because it simplifies the measurement process and makes isotope ratio measurements in atmospheric greenhouse molecule gases, e.g. CO2, N2O, CH4,
