Abstract The growth of requirements to frequency mixers adapter for high-power lasers stimulates the studies of domain kinetics in nonlinear ferroelectric crystals with the slanted polar axis. Forward domain growth after local polarization reversal by focused electron beam irradiation and domain interaction were studied in 0.5-mm-thick 36° Y-cut crystals of congruent lithium niobate. The dependences of domain length on the distance between domains and position in a block of domains were explained by the distribution of the space-charge field and domain–domain interaction. The stripe domains with length up to 500 µm were produced.

通过聚焦电子束在 36° Y 切割全等铌酸锂中局部极化反转：正向畴生长

摘要 对高功率激光器混频器适配器需求的增长激发了对具有倾斜极轴的非线性铁电晶体畴动力学的研究。在全等铌酸锂的 0.5 毫米厚 36° Y 切割晶体中研究了通过聚焦电子束照射和畴相互作用进行局部极化反转后的正向畴生长。域长度对域之间距离和域块中位置的依赖性可以通过空间电荷场的分布和域-域相互作用来解释。产生了长达 500 µm 的条纹域。
