NaCl(OH~-):(F_2~+)_H is a color center laser crystaJ with best laser performance and imPortant applications at Present. We have succeeded in develoPing this crystal and realizing its laser operation. For raising the concentration and the stability of(F_2~+)_H center, we have studied its route of formation, state, NaCl (OH ~ -): (F_2 ~ +) _H is a color center laser crystaJ with best laser performance and imPortant applications at Present. We have succeeded in develoPing this crystal and ?? its laser operation. For raising the concentration and the stability of (F_2 ~ +) _H center, we have studied its route of formation, state,
