【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更多还原

【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.更多还原
