A 3D-printed alkali metal dispenser
Abstract
We demonstrate and characterize a source of Li atoms made from direct metal laser sintered titanium. The source's outgassing rate is measured to be 5 \,(2)· 10-7\,Pa~ L~ s-1 at a temperature T=330\,, which optimizes the number of atoms loaded into a magneto-optical trap. The source loads ≈ 107 7Li atoms in the trap in ≈ 1\,s. The loaded source weighs 700\,mg and is suitable for a number of deployable sensors based on cold atoms.
