Abstract
High-precision trapping, manipulation, and detection of ions and neutral atoms are foundational to research in quantum information, simulation, and computation on AMO platforms. I will present my M.Sc. work in Prof. Groß’s group on implementing an SLM-based tweezer array and imaging system for strontium atoms in a cryogenic environment. First, I will describe the generation of a homogeneous tweezer array using a spatial light modulator in the test setup. Next, I will detail the design of a low-background imaging system that significantly reduced the red fluorescence from the high-NA aspherical objective under high-power 518 nm illumination. Finally, I will describe how I built and aligned the tweezer and imaging system on the main experiment table, leading to our first detection of atom narrow-line fluorescence in the tweezers. These developments lay the groundwork for high-fidelity, site-resolved control of strontium atoms in large tweezer arrays.
