Abstract:

The availability of high-power single-mode laser radiation at a specific wavelength and narrow spectral linewidth allows to realize novel space-borne applications including atom cooling, quantum-optical experiments on ultra-cold atoms and highly precise atomic clocks [1]. A prerequisite for implementing parts on space stations or satellites is their qualification regarding irradiation hardness, environmental endurance and operational reliability over the mission lifetime. In this presentation we report on the design, manufacture, electro-optic characterization and qualification efforts for laser modules emitting at a wavelength of λ = 767 nm at an optical power of P = 300 mW for cooling potassium (K) and λ = 1064 nm at P = 500 mW for an optical dipole trap dedicated for utilization in space [2].
