摘要
研究了双耦合场作用下的Λ-型三能级原子系统中的电磁诱导透明和电磁诱导吸收特性。数值求解相应的密度矩阵方程,给出了探测吸收曲线随耦合场参数的变化规律。通过改变耦合场的Rabi频率和频率失谐量,实现了电磁诱导吸收的频率调谐和电磁诱导透明的透明深度控制。
Both electromagnetically induced transparency（EIT） and electromagnetically induced absorption（EIA） were presented in a three-level A type configuration with double coupling fields. By numerically solving the density matrix equation of motion,the absorption profile of probe field depending on the parameters of coupling fields was demonstrated. By adjusting the Rabi frequencies and detunings of coupling fields,the spectral position of the EIA feature and the depth of the EIT feature can be controlled.
