摘要:

实验研究了泵浦光相位起伏对工作在阈值以上的非简并光学参量振荡器输出光信号模和闲频模之间相位关联的影响。利用专门设计的一对非平衡光纤Match-Zehnder干涉仪测量了纠缠光束的强度差和相位和的噪声谱。实验结果证实了理论预言,并与考虑泵浦光相位起伏的半经典理论计算结果相吻合。

英文摘要:

The influence of the phase fluctuation of the pump laser on the phase-correlation between the signal and idler modes of the output fields from as non-degenerate optical parametric oscillator operating above oscillation threshold was experimentally investigated. The noise spectra of the intensity-difference and the phase-sum of the entangled optical beams were measured with a pair of unbalanced fiber Match-Zehnder interferometers specifically designed. The experimental results proved the previously theoretical prediction and are in reasonable agreement with the calculation based on semiclassical theory involving the phase fluctuation of pump laser.
