We report room-temperature two-photon induced fluorescence of the F~2~ ^-^ color centers in LiF crystal in the βΌ960-1300 nm spectral range. The fluorescence spectra and kinetics were measured using the first (1.906 ΞΌm) and second harmonics (0.953 ΞΌm) of a H~2~βRaman Shifted single frequency Nd:YAG l
