Summary:Heat release into the operating gas of a chemical oxygen iodine laser is analyzed on the basis of stagnation and cavity pressures. The energy of excited oxygen molecules is released as heat in this device through pooling reactions, iodine dissociation, and the interactions of these processes with water vapor. The proposed estimation method is applied to the analysis of subsonic and transonic iodine injection schemes to examine energy loss during iodine dissociation. The results also provide the number n of excited oxygen molecules consumed in each iodine dissociation. The values of n were estimated to be n ≥10 and n ≥6 in the subsonic and transonic injection schemes, respectively.
