With recent advances of lab-scale optical atomic clocks, a demand for the development of transportable and miniaturized quantum-optical technology has emerged. For neutral-atom-based optical clocks, atoms from the alkaline-earth group, e.g. strontium, feature a particularly useful level structure with a strong and a narrow cooling transition and an ultra-narrow clock transition, all in the visible wavelength regime. We aim to extend the successful approach of miniaturization for alkali atom magneto-optical traps (MOT), where single-beam trapping geometries are routinely employed, to the case of strontium. Here, the challenge is to build a planar beam-shaping geometry with achromatic properties with respect to the two cooling wavelengths. Different approaches to solve this problem are presented and evaluated alongside accompanying work on laser-controlled strontium atom sources.
