论文摘要
我们通过实验表明，通过高技能腔的动态耦合模式，可以证明冷原子云的光学偶极子捕获。我们表明，陷阱需要原子的集体作用，即不会在相同的激光驱动条件下捕获一个原子。原子将模式的频率拉到更接近共振的频率，从而允许捕获腔的必要光强度。陷阱模式上原子的反作用也通过陷阱的非指数塌陷表现出来。
We experimentally demonstrate optical dipole trapping of a cloud of cold atoms by means of a dynamically coupled mode of a high-finesse cavity. We show that the trap requires a collective action of the atoms, i.e. a single atom would not be trapped under the same laser drive conditions. The atoms pull the frequency of the mode closer to resonance, thereby allowing the necessary light intensity for trapping into the cavity. The back-action of the atoms on the trapping light mode is also manifested by the non-exponential collapse of the trap.
