Paper Abstract

We have developed a rubidium atomic funnel for use as a matter-wave source in experiments in atom interferometry and atom optics. The funnel utilizes the techniques of laser cooling and trapping to produce a low-velocity beam of cold rubidium atoms. Atoms from a thermal beam are first slowed in a tapered magnetic field using 1D Zeeman slowing. The atoms are then loaded into a 2D magneto-optic trap or atomic funnel. The trap cools and compresses the atoms, which are then ejected from the trap by moving molasses formed with frequency-shifted laser beams. These slow atoms will be diffracted by microfabricated transmission gratings as part of a three-grating atom interferometer.
