- Abstract
Many experiments in the field of optical levitation with nanoparticles today are limited by the available technologies for particle loading. Here, we introduce a particle loading method that solves the main challenges, namely deterministic positioning of the particles and clean delivery at ultra-high vacuum levels as required for quantum experiments. We demonstrate the efficient loading, positioning, and repositioning of nanoparticles in the range of 100 – 755 nm diameter into different lattice sites of a standing wave optical trap, as well as direct loading of 143 – 365 nm diameter particles into ultra-high vacuum, down to an unprecedented pressure below 10 − 9 mbar. Our method relies on the transport of nanoparticles within a hollow-core photonic crystal fiber using an optical conveyor belt, which can be precisely positioned with respect to the target trap. Our work opens the path for increasing nanoparticle numbers in the study of multiparticle dynamics and high turn-around times for exploiting the quantum regime of levitated solids in ultra-high vacuum.
