Abstract
A reliable pulsed LiF:F2+ color center laser with a two-mirror cavity has been constructed. A near-infrared laser has shown a stable operation at room temperature and remarkable amplitude by pumping with the second harmonic of pulsed Nd3+-doped YAG laser. The 532 nm radiation gives rise to create the F2+ centers by ionization of the F2 centers in a process of two-photon excitation. The LiF:F2+ laser has a broadband with peak at 930 nm and half width of 40 nm. The slope efficiency is 8% and the pump threshold is 10 mW.
