Description

Recent breakthroughs with ultracold-atom-based programmable quantum simulators have started to show the potential of tweezer arrays as a quantum simulation platform.
A promising application is the simulation of many-body systems like the Ising or Hubbard models.
Our goal is to unite these two capabilities in a novel programmable quantum simulator based on the alkaline-earth atom strontium.
A crucial part is realising two-level spin systems based on ultranarrow optical clock transitions. Strontium offers various transitions suited for this purpose. We focus on the 1S0-3P2 clock transition at $671$ nm which can be magically trapped by tuning the angle of an applied magnetic field. Additionally, we plan to use the 1S0-3P0 clock transition at $698$ nm. This poster presents the generation and stabilization of the $671$ nm narrow linewidth laser light. For this purpose, a home-built external-cavity diode laser is frequency-stabilized to an ultrastable reference cavity.
Furthermore, this poster presents the layout for frequency stabilisation of the $698$ nm laser light, locked to the same cavity.
