A historical overview on the mechanism of the COIL kinetics Academic Article uri icon


  • The kinetics of the chemical oxygen-iodine laser (COIL) has been studied alongside the technological efforts in COIL development. In particular, many efforts have been devoted to the study of the mechanism of I 2 dissociation in the COIL medium. Since O 2 (a) is the energy reservoir of the COIL, it must be involved in the dissociation of I 2. Therefore, understanding the dissociation mechanism may help in finding ways of minimizing the O 2 (a) consumption for dissociation and increasing the chemical efficiency of the laser. In the present paper previously suggested mechanisms of I 2 dissociation are briefly overviewed and recent measurements and modeling of the gain and the power in supersonic COILs carried out in our laboratory are presented. Our studies employ both an analytical model and numerical calculations which are outlined in the present paper, with more details on the …
