We describe a system for loading a single atom from a reservoir into a blue-detuned crossed vortex bottle beam trap using a dynamic 1D optical lattice. The lattice beams are frequency chirped using acousto-optic modulators, which causes the lattice to move along its axial direction and behave like an optical conveyor belt. A stationary lattice is initially loaded with approximately 6000 atoms from a reservoir, and the conveyor belt transports them 1.1 mm from the reservoir to a bottle beam trap, where a single atom is loaded via light-assisted collisions. Photon counting data confirm that an atom can be delivered and loaded into the bottle beam trap 13.1% of the time.
我们描述了一种使用动态一维光学晶格将单个原子从储存器加载到蓝失谐交叉涡旋瓶形光束阱中的系统。晶格光束通过声光调制器进行频率啁啾，这使得晶格沿其轴向移动并表现得像一条光学传送带。首先，一个静止的晶格从储存器中加载大约6000个原子，然后传送带将它们从储存器传输1.1毫米到瓶形光束阱，在那里通过光辅助碰撞加载单个原子。光子计数数据证实，原子能够在13.1%的时间内被输送并加载到瓶形光束阱中。
