Future application of precision atom interferometry in space missions dedicated to Earth observation or fundamental physics, such as testing Einstein’s equivalence principle (EEP), requires robust and compact laser systems.
We present the overall architecture of a laser system at 780 nm and 767 nm for dual species atom interferometry with BECs of Rb and K on a sounding rocket. The system is designed for laser cooling of both species and simultaneous Raman- or Bragg double-diffraction interferometry. It further features a dipole trap laser at 1064 nm for mixing of the species and optical delta-kick-cooling of the matter-wave packets.
We report on technological details such micro-integrated diode lasers and advanced Zerodur optical bench technology, as well as environmental testing and system parameters relevant for dual species atom interferometry.
