Abstract
By means of radio frequency(RF) capacitively coupled discharge, pure CF3I and the mixture of CF3I and various inert gases were used to produce iodine atom for a chemical oxygen-iodine laser. The dependences of atomic iodine concentration on gas pressure and gas flow rate were studied. In the case of RF frequency of 13.56MHz, output power of 500W, gas pressure of 3.5Torr, pure CF3I without any carrier gas ,and CF3I flow rate of 1.2SLM, atomic iodine concentration of 4.0×1014 cm-3 was achieved. The concentration of atomic iodine was of the order of 0.4×1014cm-3 at p=15Torr in the case of the mixture of CF3I and some inert gases, which was lower by one order of magnitude than that of pure CF3I. A kinetics modeling was carried out and demonstrated that CF3 played dominant role in the loss mechanism of atomic iodine.
