摘要
微瓦级的He-Ne激光束在掺Mn的KNSBN晶体中实现反射全息存储,最大读出效率达60%,实验中发现耦合系数一般地不为常数,在耦合系数为常数的范围内。
Refiecting 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 μm power. It is found that the coupling factor is not always a constant and the ratios of electro-optical tensor elements are measured when the coupling factor is a constant. They are r<sub>33</sub>/r<sub>13</sub>= 0.499, r<sub>13</sub>/r<sub>42</sub>=0.0583.
