摘要
微瓦级的He-Ne激光器在掺Mn的KNSBN晶体中实现反射全息存储,最大净读出效率达60％。在本工作的实验条件下,理论和实验皆证明,用弱的物光和强的参考光可获得大的读出效率。在耦合系数为常数的范围内,测定了电光张量元之比。
Abstract
Reflecting holographic storages with a read-out efficiency of up to 60% are obtained in Mn doped KNSBN crystal by using He-Ne laser beams of uW powers. It is found theoretically and experimentally that high road-out efficiency can be realized with a weak object beam and a stong reference beam in the conditions of our experiments. The ratios of eletrooptical tensor elements of the crystal are estimated within the range of the constant coupling factor.
