Recent Updates on the ALPS II Experiment — •Gulden Othman for the ALPS collaboration — Institut für Experimental Physik, Universität Hamburg, Luruper Chaussee 149, 22761 Hamburg

The Any Light Particle Search II (ALPS II) experiment searches for axions and axion-like particles (ALPs) in an important parameter space that is relevant in understanding anomalous astrophysical phenomena, including stellar evolution. ALPS II takes advantage of the axion coupling to photons using a Light-Shining-through-a-Wall technique. Photons created using a strong laser may convert into ALPs in the presence of a strong magnetic field, traverse a light-tight barrier, reconvert into photons in another strong magnetic field, and be subsequently detected. By using two mode-matched optical resonators before and after the barrier, ALPS II aims to surpass the sensitivity of previous experiments by three orders of magnitude. In this talk, we will discuss the exciting recent progress and current status of ALPS II as we continue with our science program at DESY.
