摘要
由α切割KTP晶体组成的半整块非简并光学参量振荡腔,以倍频Nd:YAP激光器作抽运源,可在不同运转条件下获得两类非经典光场.低于振荡阈值,该系统输出最大压缩度为37dB的双模正交压缩真空态;高于阈值,产生强度差压缩度为7dB的量子相关孪生光子对.
AbstractThe configuration of a semimonolithic continuous nondegenerate optical parameter oscillator consisting of an αcut KTP crystal pumped by an intracavity frequencydoubled and frequencystabilized Nd∶YAP laser is designed. Both twomode quadraturephase squeezing of 3 7dB and intensitydifference squeezing of 7dB have been generated from the cwNOPO operating respectively below and above the oscillation threshold. The system can operate stably to generate the squeezed light for over half an hour.
