Abstract
- 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.<br />Comment: In section 4, we say that we use MOT to do experiment. However, now we realize that this experiment proposal is not sufficient. We don't consider the experimental details, such as the arrange of lasers, atomic density, etc. These things are essential important for our proposal. However, we think this difficult cannot be easily solved in short time
