摘要
研究倒Y型四能级原子与三个光场的相互作用系统,讨论了控制场不同参数下系统对探测光的吸收与色散性质。发现系统在适当条件下呈现电磁感应透明(EIT),同时系统的非线性光学特性随着外场的变化呈现丰富的变化。另外,当考虑复数拉比频率的相位变化时,系统呈现出对探测光的增益效应。
A four- level atomic system in an inverted -Y configuration interacted with three optical fields has been investigated and the properties of absorption and dispersion in different control optical fields have been discussed. The electromagnetic induced transparency would be obtained by choosing proper parameters while the optical non- linearity of the system would be changed with external fields. The numerical results also show the probe gain via changing phases of Rabi frequency.
