论文摘要
在存在强控制场的情况下，研究了具有永久性偶极矩（PDMS）的封闭环$λ$系统的弱高斯探针脉冲的传播。 PDM的存在允许多光子激发，否则禁止这种激发。 PDMS修改了探针，对照和介质内的第三个场的狂犬病频率，这显着影响了探针脉冲的传播。探针脉冲在繁殖过程中被放大，其高斯形状完整。由于未妨碍两个光子激发，因此可以在第三场的帮助下放大探针脉冲，其频率是对照场频率的两倍。
Propagation of a weak Gaussian probe pulse through a closed loop $Λ$ system with permanent dipole moments (PDMs) is investigated in presence of a strong control field along with a third field. The presence of PDMs allows multi photon excitation, which are otherwise forbidden. The PDMs modify the Rabi frequencies of the probe, control, and the third field inside the medium which noticeably affects the propagation of probe pulse. The probe pulse is amplified during propagation with its Gaussian shape intact. Due to unprohibited two photon excitation it is possible to amplify a probe pulse whose frequency is twice of the control field's frequency, with the help of the third field.
