A clock-magic quantum-gas microscope for ultracold strontium

Atomic strontium has many favorable properties for its application in quantum science and technology. A major feature is its ultranarrow optical-clock transition at 698 nm, which is often exploited in optical lattices and tweezers at a “magic” trapping condition. In this poster I present a quantum-gas microscope for strontium [1], working on a clock-magic optical lattice at 813 nm. I will describe the main features of our experimental setup and of the site-resolved imaging procedure. I will also describe a technique, based on resonant excitation, that enhances atom numbers in strontium magneto-optical traps [2].
