摘　　要：本文详细研究了ＫＢｒ晶体在室温下经氮分子激光（３３７．１ ｎｍ ）照射后所产生的双光子吸收的光谱特性及其形成机理。对着色或未着色的晶体仅照射个激光脉冲，就能产生高浓度的Ｆ色心。Spectral property and formation mechanism of two photon absorption of KBr crystals irradiated with nitrogen laser (337.1 nm) at room temperature are investigated.High density F color centers can be produced by irradiating the uncolored or colored crystals with only several laser pulses,and this method may become to a efficient way to get high density color centers for laser and optical storage.
