| 摘 要： | 为解决光束畸变问题,在前向简并四波混频布局中采用了补偿的分光技术,研究了共振介质(加碘的酒精溶剂)的简并四波混频(DFWM)效应．实验中用CCD实时连续采集DFWM信号光斑,直接从监视器上观察DFWM信号光斑．由于采用补偿分光技术,发现信号光斑位置虽然有所漂移,但信号光斑形状基本稳定,即抑制了激光漂移带来的负面影响,因而得到了稳定的DFWM信号输出；实验进一步通过对DFWM信号光与泵浦光光场分布的测量验证了补偿分光技术的有效性

| Abstract: | Degenerate four-wave mixing ( DFWM) using forward geometries has been investigated in resonant medium ( iodine solution) by using compensated beam-split technique to stabilize the light path. Experimentally real-time CCD has been used to collect signal spot of DFWM, which directly is detected on monitor. Because compensated beam-split technique (CBST) is used to compensate the beam excursion caused by the laser itself and disturb of the environment, steady DFWM signals have been obtained; the effect of CBST has been proved in the distribution of DFWM signal light and pump light in the experiment. |
