Trapped ions present a promising platform for quantum simulations. Versatile and robust laser systems with narrow bandwidth and high power and intensity stability are required for reliable control of this platform. The latest systems for Mg⁺, Be⁺ ions are based on vertical external cavity surface emitting lasers (VECSEL)[1] in the near-infrared. We are testing new compact cooling systems with impact on short-term frequency stability using commercially available PC parts. With the goal of measuring magnesium ions at a frequency stability of 200 kHz ( λ ≈ 1120 nm, P=2 W) with high accuracy. We aim at further development of the VECSEL into a compact, stable and user-friendly "turnkey" system.
