Laser systems with precise and accurate frequencies are one of the key elements in modern precision experiments based on atom interferometers and atomic clocks. Future space missions including quantum interferometry based gravity mapping, tests of the equivalence principle or the detection of gravitational waves rely on robust and compact lasers with high mechanical and frequency stability.
Here we present a compact diode laser system for atom interferometry with ultra-cold atoms aboard sounding rockets. Our laser system is flight-proven through successful operation in the MAIUS mission. Design, assembly and qualification of the laser system as well as its performance during the flight are discussed.
