本文介绍Fe:LiNbO3晶体在波长为6328?的低功率激光下的简并四波混频(DFWM)现象。给出了在不同泵浦功率下,共轭波强度随照射时间变化的实验曲线。验证了共轭波的位相补偿特性,并利用该特性校正了位相畸变的图象,得到了与理论相一致的实验结果。This paper reports a degenerate four-wave mixing effect in Fe-doped LiNb03 crystal at low laser power (He-Ne laser, λ=6328?). The experimetal curves about intensity of conjugate wave vs. irradiate time at different pump power is given. The phase-compensated property of the conjugate wave was examined, and the phase distortion image was corrected by means of this property. The experimental results obtained agree with the theory.
