摘　　要：研究了Airy光束(Airy beams)在电磁感应透明(Electromagnetically induced transparency,EIT)介质中的传输性质。利用ABCD矩阵光学理论,推导出Airy光束在EIT介质中的传输解析表达式。计算结果表明,Airy光束的自加速偏转和光强分布都可以通过控制光的拉比频率调控。该研究结果对利用Airy光束在光学操控以及生物医学中的应用都具有十分重要的潜在应用价值。The propagation properties of Airy beams passing through an EIT vapor were investigated. The analytical expression of Airy beam passing ABCD system of the EIT vapor was deduced and employed to analyze the propagating quantity of the beam. It is shown that both the deflection position and intensity of Airy beam can be modulated by Rabi frequency of the control light. Such a tunable optical behavior may have some potential applications in biomedical science and optical manipulation.
