用一种简单、廉价的工艺在钠钙浮法玻璃中制作了一种衍射光学元件。玻璃夹在网状阳极(点阵常数2微米)和平板金属阴极之间。在553K的适度高温下施加直流电，会引起玻璃的热极化。结果是，当电场导致玻璃和电极之间有接触的离子贫化区域时，电极的结构图案被压印在玻璃上。给出了结构过程的电流-时间动力学，以及X射线元素分析和电导率测量。对所得样品的衍射图的光学分析表明，可以制造出大规模和复杂的图样。(C)2015年美国光学学会
A diffractive optical element is fabricated in soda-lime float glass using a simple and inexpensive process. The glass is sandwiched between a mesh anode (lattice constant 2 mu m) and a flat metal cathode. Applying a direct current while at a moderately elevated temperature of 553 K induces thermal poling of the glass. The result is that the structured pattern of the electrode is imprinted on the glass as the electric field causes ion depleted regions where there is contact between the glass and electrode. The current-time dynamics of the structuring process along with X-ray element analysis and conductivity measurements are presented. Optical analyses of the resultant diffraction patterns of samples suggest that large-scale and complex patterns can be fabricated. (C) 2015 Optical Society of America
