V originále
Laser induced fluorescence was used for measurement of concentration of hydroxyl (OH) radicals in the plasma pencil, which is a radiofrequency plasma jet operated in argon at atmospheric pressure. The problematic of the rotational energy transfer, spectral overlap of the laser line and hydroxyl absorption line and saturation effects were treated. The method was calibrated by Rayleigh scattering on the ambient air. The concentration of hydroxyl radicals in the effluent of the plasma pencil was found to be in the order of 10 to 20 per cubic m. Dependence of hydroxyl concentration on argon flow rate and RF power delivered to the plasma were measured. Thy hydroxyl concentration was maximum at conditions, when the measurement point was close to the tip of the visible active discharge.
