Stable generation on F+2- and F3-Like color centers in LiF:OH and Li:Mg crystals under pumping by radiation with wavelengths of 0.599 and 0.608 μm

The crystal laser media LiF:OH and LiF:Mg with F + 2 and F 3 color centers modified by impurities are investigated under the conditions of power optical pumping. Dependences of the relative quantum output luminescence of the laser-active F 3 Mg 2+ V - c color centers are measured versus the dose of γ radiation and the wavelength of stimulating light for a LiF:Mg crystal. It is shown that optical pumping in the spectral region 0.599-0.608 μm does not cause degradation of the investigated active media.
