通过联立两中心带输运物质方程和双光束耦合波方程 ,建立了双掺杂LiNbO3 晶体采用双色光 (紫外敏化光和He Ne记录光 )实现非挥发性全息存储的动力学模型。理论上分析了深、浅两杂质中心的微观光学参量 (包括敏化光的深中心和浅中心光激发系数、记录光的浅中心光激发系数以及深中心和浅中心的电子复合系数 )对记录饱和衍射效率和固定衍射效率的影响。数值计算表明 ,在双掺杂LiNbO3 晶体的非挥发性全息存储中 ,为了得到高的固定衍射效率 ,应该选择复合系数较大、记录光激发系数较高、敏化光激发系数较低的浅杂质中心以及敏化光激发系数较高、复合系数最佳的深杂质中心。 The kinetic model of non-volatile holographic storage in dual-doped LiNbO3 crystal using two-color light (UV-sensitized light and He Ne recording light) was established by using the simultaneous two-center transport equation and dual-beam coupled wave equation. The micro-optical parameters of deep and shallow impurity centers were theoretically analyzed (including the deep center and shallow center light excitation coefficients of sensitized light, the shallow center light excitation coefficient of recording light and the deep center and shallow center electron recombination coefficients) Saturated diffraction efficiency and fixed diffraction efficiency. Numerical calculations show that in the non-volatile holographic storage of double-doped LiNbO3 crystals, in order to get high fixed diffraction efficiency, shallow impurities with larger recombination coefficient, higher recording light excitation coefficient and lower sensitized light excitation coefficient Center and sensitized light excitation coefficient is higher, the composite coefficient of the best deep impurity center.
