摘要
建立了包括扩散、漂移和光伏打三种输运机制下双掺杂uNbo3晶体在用双色光进行光存储的带输运方程,并得出了小调制度下稳态空间电荷场的分析解。对双色光的光强比、体光栅的波矢、双掺杂的浓度和晶体的氧化还原程度对空间电荷场的影响进行了数值计算和讨论。
Abstract
By taking into account of diffusion, drift and the photovoltaic effect, the band transport equations are set up when the volume holography is recorded in doubly doped LiNbO 3crystals by using two color lights, and obtain the analytical solution of the steady state space charge field. The effects of the ratio of intensities of two color lights, the grating wave vector, the doubly doped concentrations and the oxidation reduction state on the steady state space charge field are calculated and discussed.
