By jointly solving the two center material equations and the coupled wave equations, a dynamic model to study the nonvolatile hologram realized by the two color recording scheme (UV light for sensitizing and He Ne laser for recording) in doubly doped LiNbO 3 crystals is set up. The aim is to study the effects of the microscopic optical parameters of the deep and shallow doping centers on the saturation and fixed diffraction efficiencies. These parameters include the photo excitation coefficients of deep and shallow centers for sensitizing light, the photo excitation coefficient of shallow center for recording light, and the electron recombination coefficients of deep and shallow centers. Numerical solutions show that, for the nonvolatile holographic storage in doubly doped LiNbO 3 crystals, in order to obtain high fixed diffraction efficiency, one should select the shallow center with large electron recombination coefficient, with high photo excitation coefficient for recording light and with low photo excitation coefficient for sensitizing light; and select the deep center with high photo excitation coefficient for sensitizing light and with optimal electron recombination coefficient.

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 ultraviolet-light-induced absorption UV-LIA coefficient change is investigated in congruent LiNbO_3 crystals doped with Mg~ 2+ of different concentrations.By measuring the UV-LIA coefficient change and the two-color recording sensitivity in congruent LiNbO_3∶Mg,it is found that the UV-LIA coefficient change in congruent LiNbO_3∶Mg has a threshold effect with respect to the Mg~ 2+-doping concentration.It is only when the molar fraction of Mg~ 2+ is more than 3.0% that the UVLIA change from the near-UV...

The ultraviolet-light-induced absorption UV-LIA coefficient change is investigated in congruent LiNbO_3 crystals doped with Mg~ 2+ of different concentrations.By measuring the UV-LIA coefficient change and the two-color recording sensitivity in congruent LiNbO_3∶Mg,it is found that the UV-LIA coefficient change in congruent LiNbO_3∶Mg has a threshold effect with respect to the Mg~ 2+-doping concentration.It is only when the molar fraction of Mg~ 2+ is more than 3.0% that the UVLIA change from the near-UV to the near-infrared spectral regions appears.The threshold behaviour is further confirmed by the measurement of the two-color recording sensitivity.This threshold molar fraction is lower than the so-called optical damage-resistant threshold concentration of 4.6% in LiNbO_3∶Mg.The UV-LIA absorption effect is assumed to be related to the decrease and even elimination of the antisite defect Nb_ Li in LiNbO_3∶Mg.

研究了同成分掺镁铌酸锂晶体中的紫外光致吸收效应。通过对不同掺Mg浓度铌酸锂晶体的紫外光致吸收系数和双色存储灵敏度的测量,发现同成分掺镁铌酸锂晶体的紫外光致吸收效应具有Mg离子浓度阈值效应。只有当掺Mg摩尔分数大于3.0%时,从近紫外一直延伸到近红外波段的紫外光致吸收效应才显示出来。这一Mg离子浓度阈值效应进一步为双色存储灵敏度的测量结果所证实。该浓度阈值小于掺镁铌酸锂晶体抗光损伤效应的摩尔分数阈值4.6%。这种紫外光致吸收现象可能和掺镁铌酸锂晶体中反位铌NbLi浓度的急剧减少基本消失有关。

We multiplex 20 plane-wave holograms in LiNbO_3:Fe:Cu crystal with recording beams at 633 nm and gating beam at 365 nm.Their average fixing efficiency reaches 79 %,and after-fixing dynamic range M/# is 1.50.The effect gating intensity,and intensity ratio of writing to gating beam on two-color recording performances of multiplexing holograms in LiNbO_3:Fe:Cu crystal is investigated.The experimental results show that the decrease of the intensity ratio of writing to gating beam and the increase of the gating intensity at the same time will result in higher average fixing efficiency and dynamic range.On the other hand,the experimental results indicate that the higher the intensity ratio of writing to gating beam,the higher recording sensitivity.

采用365 nm的门光束和633 nm的记录光,在LiNbO3:Fe:Cu(Fe:0.15%;Cu:0.01%)晶体中实现了20幅全息光栅的双色复用记录和固定,平均固定效率达到79%,在5.0 mm厚的晶体中固定后的动态范围M/#为1.50。实验研究了门光束光强、记录光与门光束的光强比对双色复用存储性能的影响,结果表明,增大门光束光强、减小记录光与门光束的光强比,有利于提高双色记录的复用全息图的平均固定效率以及动态范围;而增大记录光与门光束的光强比,可以提高双色记录灵敏度。
