From the numerical simulation and the steady-state solution to the density matrix equations, we find that AWI can be realized by choosing theintensities of the pumping and the magnetic fields and the relative phase of the probing and the pumping fields.

 
  • 从密度矩阵方程出发,对三个态的粒子数进行了数值模拟,并得到了密度矩阵方程的稳态解,由稳态解得到了实现无反转放大的条件。 适当选取泵浦光场的Rabi频率和相干磁场的Lamor频率以及探测光场和泵浦光场之间的相对相位,可以在此系统中实现无反转放大。
