The MAIUS 2/3 missions aim for high-precision tests of Einstein's Equivalence principle by means of dual-species atom interferometry (AI) with BEC's of rubidium and potassium on a sounding rocket. While this platform features long microgravity times, it puts high demands on the compactness, robustness and agility of the experiment and requires a concept for autonomous operation.
In this poster, we present a laser system based on micro-integrated diode lasers that is designed for cooling, state preperation and simultaneous Raman double-diffraction interferometry to probe for differential accelerations. We report in detail on our concept for autonomous and agile frequency control of phase-locked extended cavity diode lasers (ECDL) in a dual-use configuration for laser cooling and Raman interferometry. Furthermore, we present results of environmental and performance tests of the laser system.
