In order to adjust and broaden the absorption spectrum and emission spectrum of the (F 2 + )H type color center so as to match up to the pumping and to fit in with the demand of application, a (KBr‐KCl)(OH − ):(F 2 + )H color center laser crystal series was prepared by the process of single crystal growth, additive coloration, anneal, and light aggregation at 290 K and 77 K. The spectral characteristics of (KBr‐KCl)(OH − ) crystals are investigated. It is found that the absorption and emission band of the (F 2 + )H color centers in KBr‐KCl complex host crystals has a considerable adjustment and extensions compared to the color centers in single KBr or KCl crystal.
