Dissociation of molecular iodine in RF discharge for oxygen-iodine laser

Popis výsledku v původním jazyce

The dissociation of molecular iodine in 40 MHz-RF discharge was studied xperimentally. This generation of atomic iodine is aimed at use in oxygen-iodine lasers. The discharge was ignited in a mixture of I2 + buffer gas fast-flowing through the cylindrical chamber and the discharge products were injected into a supersonic flow of nitrogen. Argon and helium were used as a buffer gas; a discharge stability and dissociation efficiency were better with argon. At the I2 flow rate corresponding to the operation of a 1 kW chemical oxygen-iodine laser, the dissociation fraction was about 20%. The dissociation efficiency significantly decreased with increasing in the specific energy. At a reasonable I2 flow rate (0.32 mmol/s), the maximum achieved efficiency was8.5% and the corresponding energy cost was 8.9 eV per dissociating of one I2 molecule. The obtained dependencies on the gas flow rates infer a good chance for scaling-up of the tested RF discharge generator for the intended application.
