摘要提出一种在光学参量振荡腔中的量子态频率上转换的方案.方案分析了信号传递系数和转换效率随不同泵浦参数的变化情况,并定性和定量地阐述了频率上转换过程的量子性质.研究表明,泵浦参数在阈值以上并接近阈值时,量子态的转换频率可达到最大值. This paper presents the scheme of the quantum state transfer via nondegenerate optical parametric oscillator.Analysis of the change of the transfer coefficient and conversion efficiency on the pump parameter,expatiation on the characterization of quantum frequency conversion process on the qualitative and quantitative.Frequency conversion efficiency of quantum states can be the maximum to closer to the threshold as long as the frequency conversion via operating optical parametric oscillator above the threshold.
