Sumario:Optical clock transitions are exceptionally accurate measurement tools, essential for various applications like precise timekeeping, testing fundamental physics constants, and performing quantum simulations of many-body physics. Addressing these transitions requires stable and well-controlled laser systems. This thesis presents the development of such a laser system, specially designed to address the strontium clock transition for quantum simulations. The work involves the design and construction of an optical setup for coupling an external-cavity diode laser of wavelength 698 nm into a Fabry-Pérot cavity and the application of the Pound-Drever Hall locking technique for frequency stabilization. The work also addresses the implementation of a vibrational isolation stage to mitigate external vibrations on the cavity and an isolation box for acoustic and thermal stability. By integrating advanced optical and electronic methods, the precision and stability of the clock laser are significantly improved.
