Abstract

We demonstrate a two-dimensional grating magneto-optical trap (2D GMOT) with a single input cooling laser beam and a planar diffraction grating using 87^{87}Rb. This configuration increases experimental access when compared with a traditional 2D MOT. As described in the paper, the output flux is several hundred million rubidium atoms/s at a mean velocity of 16.5(9)16.5(9) m/s and a velocity distribution of 4(3)4(3) m/s standard deviation. We use the atomic beam from the 2D GMOT to demonstrate loading of a three dimensional grating MOT (3D GMOT) with 2.46(7)×1082.46(7)\times 10^8 atoms. Methods to improve output flux are discussed.
