Paper Abstract

The electronic transition IF B3 ?(0+)--> IF X1?+ is accompanied by a radiative emission in the vicinity of 625 nm. The possibility of using this transition in a chemical laser through direct production of the B state is estimated. A computer code has been developed and applied to a kinetic scheme also described. It has been observed that a population inversion between IF B 3?(0+), v’=0 and IF X1?+ v"=5 can be achieved. IF B is obtained by mixing I (2 P 3/2) plus F (2 P 3/2) with O2 (1 ?). Atomic species are produced directly by only one combustion followed by frozen expansion. A set up is proposed to demonstrate the laser effect. The characteristic time of mixing and the population inversion lifetime are so close, that an optimization of the injection and mixing conditions is necessary. In a first experimental step to demonstrate laser effect, the iodine planar laser induced fluorescence technique allowing the visualization of mixing flows was used to qualify and to optimize the injection device.
