The advent of commercially viable quantum computation will critically improve our ability to solve hard optimization problems. This requires an easily scalable and stable platform, for which neutral atom based systems are a promising candidate. As core components of such quantum computers, the generation and control of homogeneous trapping arrays as well as their deterministic loading are of particular interest.

Here, we report on the generation of large arrays of optical tweezers with a Spatial Light Modulator (SLM). We characterize the tweezer array and quantify the limitations imposed on the patterns by our experimental conditions. Furthermore, we present a method for characterizing a sorting beam controlled by two separate acousto-optic deflectors and the response of the beam to different forms of radio frequency ramps and different ramping speeds.
