Preparation of NaCl color center laser crystals and perturbation effect of ions
NaCl:(F-2(+))(AH)-type color center laser crystals were prepared by the crystal growth, additional coloration, annealing, and by light aggregation at 290 and 77 K. The formation process of color center in NaCl crystals were investigated, the influence of doped cation and anion ions on the stability and optical properties of color centers is discussed in this paper.
