摘要
为了研究余弦高斯光束通过电磁感应透明介质的传输特性,利用衍射积分理论推导出余弦高斯光束通过电磁感应透明介质光强的解析表达式。利用该解析表达式得到了余弦高斯光束通过电磁感应透明介质的光强。计算结果表明,余弦高斯光束的光强可以通过电磁感应透明介质的拉比频率调控。此研究结果提供了一种调控余弦高斯光束光强的新方法和技术。
In order to study the propagation characteristics of cosine-Gaussian beams through a electromagnetically induced transparency medium, the analytical expression is obtained for the intensity function of a cosine-Gaussian beams passing through the electromagnetically induced transparency medium based on the diffraction integral theory. The intensity of the beam through the electromagnetically induced transparency medium is obtained by using the formula. Numerical examples show that the intensity of the cosine-Gaussian beams can be modulated by the Rabi frequency of the electromagnetically induced transparency medium. The resultsprovide a new method and technique for modulating the beam intensity
