提出用ＣＯ２激光对记录于ＬｉＮｂＯ３晶体中的全息进行实时实地地局域热固定。通过脉冲加热和加载吸热体，可以使得温度范围在１００～２００℃之间的区域接近于加热光的形状，分布于一局部范围。文中给出了加热模型及其数值解。通过得到的最优解参数进行了一系列实验。实验结果显示，用ＣＯ２激光可以成功地对光折变全息进行实时实地地局域热固定，并且加热时间短、固定转换效率较高。
It is proposed that real-time and localized local heat fixation of holographic recorded in LiNbO3 crystal by CO2 laser. By pulsed heating and loading of the heat absorbing body, it is possible to bring the region in the temperature range between 100 and 200 ° C close to the shape of the heating light and to distribute it in a partial region. In this paper, the heating model and its numerical solution are given. A series of experiments were carried out with the optimal solution parameters obtained. The experimental results show that CO2 laser can successfully localize the photorefractive holography in real time, and the heating time is short and the conversion efficiency is high.
