The quality and the growth rate of diamond films produced in a microwave bell jar plasma reactor are strong functions of the plasma characteristics at the plasma-surface interface (temperatures, species concentrations). These local parameters are sho

CARS spectra of the ν 1 band of water vapour at room temperature and 2100 K over a large pressure range (200-19 × 10 5 Pa) were studied experimentally and theoretically. The influence of N 2 and H 2 O on the rotational relaxation processes of H 2 O

Some of the most representative results of the coherent anti-Stokes Raman spectroscopy research program on discharges at ONERA are presented. A very short review of the principles of CARS and of the main instrumental characteristics is first given. T

A CARS method, adapted for diagnostics in low-pressure unsteady flows is described. The technique employs two narrow-band dye lasers and a single-frequency pump laser. Single-shot rotational temperature is obtained from the ratio of the intensities o

The rotational temperature of the excited state O2 (b1 Sigma g+, v=0) in an oxygen glow discharge is measured from the intensity distribution of the atmospheric A-band O2 (b1 Sigma g+, v=0) to O2(X3 Sigma g-, v=0) at lambda =760 nm. The kinetic tempe
