Enhancement of LiF:F3+ centers with N2 laser irradiation
High density F3+ centers can be produced efficiently by irradiating the colored LiF crystals with nitrogen laser (337 nm) at liquid-nitrogen temperature. The experimental procedure, speotroscopio properties and formative mechanism of the second creation of F3+ centers in the crystals are described in great detail.
