摘要
Neutral atoms trapped in microscopic optical tweezers have emerged as a growing platform for quantum science. Achieving homogeneity over the tweezers array is an important technical requirement, and our research focuses on improving it for holographic arrays generated with a spatial light modulator. We present a series of optimization methods to calculate better holograms, fueled by precise measurement schemes. These innovations enable to achieve intensity homogeneity with a relative standard deviation of 0.3%, shape variations below 0.5%, and positioning errors within 70 nm. Such ultraprecise holographic optical tweezers arrays allow for the most demanding applications in quantum science with atomic arrays.
