摘要
首次报道了在纯紫膜LB膜中实现光学相位共轭输出的实验现象,并在理论上从简化的菌紫质分子光循环模出发,导出了共轭光强度与总入射光强度之间的关系,最后用拟合方法求得这种紫膜LB膜的饱和吸收强度为0.49W/cm^2,bR分子处于中间体M(410)上的寿命为2.5ms左右.
We report an observation of optical phase conjugate in LB films of pure purple membrane for the first time. The dependence of intensity of the optical conjugate wave upon the total incident intensity has been deduced, based on the simplified model of
photo-cycle of bacteriorhodipsin [bR (570) M(410)]. The fitting restults of the saturated absorption intensity of the LB films and the life time of the intermediate M (410) are 0. 49 W/cm2and 2. 5 ms, respectively.
