Laser systems with precise and accurate frequencies is the key element in high precision experiments such as atom interferometers and atomic clocks. Future space missions including quantum based tests of the equivalence principle or the detection of gravitational waves will need robust and compact lasers with high mechanical and frequency stability.
We present a new generation of compact laser systems optimized for precision measurement applications with ultra-cold atoms aboard sounding rockets. Design, assembly and qualification of a system capable of atom interferometric experiments with degenerate 87Rb in context of the MAIUS mission will be discussed.
Laser spectroscopy payloads for two other sounding rocket experiments are also presented. FOKUS, which will operate together with a rocket-borne frequency comb on the TEXUS 51 mission and KALEXUS, a laser system containing two narrow linewidth extended cavity diode lasers (ECDLs) for potassium spectroscopy. All laser systems are to be launched within the next 12 months.
