| 摘 要： | 本文报道首次在红外区用Stark开关技术观测了光学旋转回波效应。光学旋转回波是光学章动的再现,具有较长的弛豫时间,可用来研究许多与弛豫过程有关的物理现象。由于采用了Stark开关技术和由微处理机控制的同步触发及数据截取系统,改善了实验条件,提供了理想的相移,得到了较好的结果。同时,推广了Bloch方程的普遍解,导出了光学旋转回波的精确表示式。最后指出了这一效应的一个重要用途。

| Abstract: | The observation of optical rotary echos by Stark switching in infra-red region is reported. Optical rotary echo is a nutation echo and has a long relaxation time which makes it particularly useful in the study of relaxation process. An improvment of experimental condition has been made and a theoretical calculation of rotary echo is presented. |
