摘要/Abstract

摘要： 实验研究了质子辐照的KNbO₃晶体随光强变化的光折变响应特性，并测量了其光折变时间常数。实验结果揭示出在质子辐照后的KNbO₃晶体中存在着2种不同的光栅，其一是慢成分，是由晶体本身的光折变效应所产生；另一个则是快成分，是由于质子辐照后所产生的辐照效应。实验结果还反映出这2种光栅是由2种不同种类的载流子产生的。

关键词: 离子辐照, 光折变效应, 响应时间

Abstract: The experimental investigation on the intensity-dependent photorefractive response of the proton-implanted KNbO₃ crystals is presented. The decay time constant was measured. The results revealed that two gratings existed simultaneously, one was caused by the photorefractive effect, and the other was contributed from the proton-implantation. The experimental results also reflect that low dose implantation hardly influence the photorefractive decay time.

Key words: ion implantation, photorefractive effect, response time
