Abstract F2 centers in colored undoped and doped NaF crystals can be converted nearly completely into F2+ centers with the high density of more than 1017cm-3 by irradiating the crystals with a 505nm laser at room temperature. A process of conversion from F2+ to (F2+)* centers in the NaF crystals doped with divalent metal ions such as Mn++, Mg++ and Ni++ after the 505nm laser irradiation was observed in our experiments.
