Abstract
A method for producing molecular Iodine for introduction into the laser cavity of a Chemical-Oxygen-Iodine-Laser (COIL) includes the step of preparing a solid mixture that contains a primary component and an additive component. The solid mixture is formulated to generate a gas having a high concentration of molecular Iodine when ignited. The primary component of the mixture is composed of oxidizer and fuel at a substantially stoichiometric ratio and includes at least one Iodine compound. The additive component is provided to cool the relatively high temperature gas that is created during combustion of the primary component. The result is a gas at a relatively low temperature in which most of the Iodine is present as molecular Iodine. The additive component is preferably an Iodine compound that either absorbs heat during decomposition such as Iodine Pentoxide (I2O5) or an Iodine compound that absorbs heat during sublimation such as solid Iodine.
