摘要

强太赫兹脉冲和二次谐波产生过程是在皮秒时间尺度上激发和研究磁有序系统、铁电体和多铁体的超快动态响应的有前途的方法。本文报道了电场强度高达20 MV cm−1的强太赫兹脉冲在中心对称反铁磁NiO中产生二次光谐波的实验结果。

Study of second optical harmonic generation in terahertz pulse-induced antiferromagnetic NiO

Intense terahertz pulses and a process of second harmonic generation are promising methods for exciting and studying an ultrafast dynamic response in magnetically ordered systems, ferroelectrics, and multiferroics on the picosecond time scale. In the present work, we report experimental results on generation of second optical harmonic in centrosymmetric antiferromagnetic NiO induced by intense terahertz pulses with an electric field strength of up to 20 MV cm−1.
