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 KILi and RbILi 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 KlLi and RbILi, or in comparable crystalline materials by growing, coloring, and annealing the KLi or the RbILi crystals in nitrogen-free inert e.g., argon atmospheres.
