| Abstract: | The sensitive detection of H2 molecules was demonstrated by means of twophoton excited laser-induces fluorescence spectroscopy with a narrow-band ArF excimer laser. A detection limit of 2×1014 cm–3 was obtained with an excitation power of  150 kW. This is already comparable with that obtained by the coherent anti-Stokes Raman scattering (CARS). This technique was successfully applied to measure a spatial distribution of H2 in a town-gas burner. |
