Abstract : A related object of the invention is to successfully produce laser-active lithium-fluorine centers in additively-colored Potassium iodide lithium iodide, Rubidium iodide lithium crystals and other comparable crystalline materials, especially materials doped with lithium (Li). A principal object of the invention is to provide and produce additively-colored KI:Li and RbI:Li crystals in which fluorine ion color centers which can be regenerated at will; these crystals and a method of manufacturing these crystals are provided by the invention. Another object of the invention is to create fluorine ion centers in Kl:Li and RbI:Li, or in comparable crystalline materials; by growing, coloring, and annealing the K::Li or the RbI:Li crystals in nitrogen-free inert (e.g., argon) atmospheres.
