【摘要】 本文对用电子束扫描ＬｉＮｂＯ３晶体的负畴面实现畴反转进行了实验研究。对于不同的扫描电压、扫描电流和扫描速率得到了不同的畴反转宽度，并且研究了畴反转宽度与扫描参量之间的关系。对畴反转的机理也进行了探讨更多还原

【Abstract】 Experimental studies on the domain inversion in LiNbO 3 crystal by electron beam scanning were performed.With different scan beams,acceleration voltages and scan rates,we get different domain widths.The relationship between the inverted width and scan parameters was investigated.The domain inversion mechanism was also discussed roughly.更多还原
