石英玻璃 电场极化 二次谐波发生 偶极子取向 fused silica electric field poling second harmonic generation dipole orientation
摘要
报道了电场极化条件对石英玻璃的电致二阶非线性光学效应的影响的研究结果。通过实验发现,石英玻璃经较高温度下的电场极化作用所产生的二次谐波发生与极化温度、极化电压具有相关性,并表现出一定的规律性:在一定的极化电压下,二次谐波强度在某一适中的温度下达到极值;在一定的极化温度下,二次谐波强度随极化电压的增大而逐渐增强,并渐趋饱和。根据玻璃的电致二阶非线性极化的“偶极子取向”模型,解释了实验结果。
Abstract
In this paper, reported is influence of the electrical poling conditions on the electroinduced second order nonlinearity in fused silica. It is found that the second harmonic generation in fused silica caused by electrical poling at elevated temperature is dependent upon the electrical poling temperature and voltage. By poling glasses with a certain voltage, the SHG intensity acquires a maximum value at a moderate temperature, while the SHG intensity increases with the rise of poling voltage and reaches the saturation gradually when the poling temperature is fixed. The experimental results can be explained reasonably by the dipole orientation model for the electroinduced second order nonlinear polarization in glasses.
