A cw/pulsed RF discharge coupled by electrodes in coaxial arrangement is used to dissociate iodine atoms from CH3I or CF3I molecules diluted in a carrier gas (a mixture of Ar and He). The discharge chamber is arranged directly inside an iodine injector of laser to minimize the recombination of generated atomic iodine before its injection into the supersonic flow in laser cavity. Measurements of I atoms concentration are done by means of absorption measurements at the wavelength of 1315 nm in dependence on basic RF discharge parameters and flow mixing conditions.
