Abstract

A planar triplet of diffraction gratings is used to transform a single laser beam into a four-beam tetrahedral magneto-optical trap. This “flat” pyramid diffractor geometry is ideal for future microfabrication. We demonstrate the technique by trapping and subsequently sub-Doppler cooling Rb87 atoms to 30μK.

(a) Top view of three gratings and the circular vertical incident beam. The arrows show the blaze direction. (b) Side view of a first-order diffracted beam, illustrating geometric beam compression. Tomographic movies of the beam overlap volume for (a) are shown in Media 1.

Fig. 2

Relative grating MOT radial trapping strength compared to the tetrahedral PMOT [7], η S P , as a function of the intensity ratio I S P and relative phase ϕ S P between the S and P components of the first-order beams at the MOT location. The outer black and inner red curves indicate 50% and 70% relative trapping strength, respectively.

Fig. 3

Photograph of the experimental setup from the side. The MOT forms in the overlap of the downward incident beam (dashed white lines) and the three first-order grating beams. The path of the diffracted beam (dotted white lines) from one grating (yellow schematic appearing as a short rectangle in the lower right) refracts through the 3-mm-thick quartz vacuum cell (blue long rectangle that extends across the figure), then propagates at the expected α 69 ° .
