【Abstract】 The color centers in higher purity LiF crystals can be obtained byγ-ray in radiation.High densities of F₂（?） centers can be formed by selecting the irradia-tion.dose of 4x10’Rad.The F₂（?）centers are converted subsequently to high density F₂₊centers by twostage photoionization.As a result, the laser output of near IR pulsesis relatively steady with F₂⁺ centers obtained in this way,更多还原
