摘要
在真空场诱导相干和非相干抽运场作用下梯形三能级原子系统的折射率和吸收性质会发生改变,呈现零吸收高折射率现象.零吸收对应的折射率值可以通过改变非相干抽运场的抽运速率和偶极矩阵元间的夹角加以调控.
The refraction-absorption properties in a three-level ladder-type system with vacuum-induced coherence and inco.herent pumping was studied.It shows that the high index of refraction without absorption can be achieved.And the refractive in.dex without absorption can be controlled by choosing the proper values of the incoherent pumping and the angle between the two dipole moments.
