Diffraction gratings for atom cooling produced by direct laser writing
ORAL
Abstract
We report the use of a direct laser-writing process to fabricate a 2D diffraction grating that can form a magneto-optical trap from a single laser beam. This approach significantly speeds up the fabrication process of these gratings compared to the conventionally used electron-beam lithography approach [1]. We also discuss the effects of imperfect suppression of higher-order diffractions — arising from the resolution limits of the direct laser writer — on the trapping and cooling region of the MOT.
