| 摘 要： | 从理论分析了N型四能级原子系统中自发产生相干及外加激光场的强度变化对电磁感应透明和Kerr非线性效应的影响.结果发现,自发产生相干的存在能够使得Kerr非线性显著增强,随着其增强,Kerr非线性的峰值逐渐增强且进入电磁感应透明窗口内.此外,在自发产生相干系数极大时与不存在时相比,Kerr非线性能够增强l0倍.研究还发现...

| Abstract: | A theoretical investigation of the effect of spontaneously generated coherence and the applied laser field intensity on the electromagnetically induced transparency and Kerr nonlinearity is carried out.It is found,with spontaneously generated coherence present,the Kerr nonlinearity can be clearly enhanced is carried out,and the maximal Kerr nonlinearity does not only enter the electromagnetically induced transparency window as the spontaneously generated coherence intensitifies,but also gets enhanced about ... |
