摘要
基于非相干泵浦四能级原子系统,提出了一种调控增强古斯-汉欣位移的新方法,实现了负折射率效应。研究结果表明:选取合适的驱动场拉比频率、场失谐量及入射角,可以使古斯-汉欣位移达到350λ,且可以调控古斯-汉欣位移的正负。
Based on the incoherent pumped 4-level atomic system, a new method for regulating the enhanced Goos-H nchen shift is proposed, which realizes the negative refractive index effect. The results show that the Goos-H nchen shift can reach 350 order of wavelengths, and the positive and negative of the Goos-H nchen shift can be adjusted by selecting the Rabi frequency, field detuning, and the incident angle of the driving field.
