We theoretically investigate atomic cooling using a spatially varying AC Stark shift to compensate for the changing Doppler shift of an unchirped cooling beam. An integrated approach using waveguide-based atom photonics is ideal to achieve the required spatial tailoring of the AC Stark beam intensity. We present two examples of the design procedure to cool sodium atoms in hollow-core antiresonant reflecting optical waveguides over tens of centimeters resulting in final velocities comparable to a Zeeman slower. The methods presented here are applicable to other experimental arrangements and atomic species.
