论文摘要
在本文中,我们提出了一种基于黑态的诱捕策略,以打破显微镜的光学衍射极限。我们利用具有时间和空间调制的空间依赖性耦合场和一个探针激光场与三级原子相互作用。时间调制使我们能够在点扩散函数的一半最大(FWHM)下降低全宽度,并且空间调制有助于我们获得比高斯光束更好的空间分辨率。此外,我们还提出了原理证明实验方案并讨论其可行性。
In this paper we propose a dark-state-based trapping strategy to break the optical diffraction limit for microscopy. We utilize a spatially dependent coupling field and a probe laser field with temporal and spatial modulation to interact with three-level atoms. The temporal modulation allows us to reduce the full width at half maximum (FWHM) of point spread function, and the spatial modulation help us obtain better spatial resolution than Gaussian beam. In addition, we also propose a proof-of-principle experiment protocol and discuss its feasibility.
