The paper presents the first implementation of a 2D GMOT with a planar diffraction grating and single laser input, simplifying setup and increasing atom flux compared to traditional methods.

## Key findings

- Output flux of several hundred million atoms/sec
- Mean atom velocity of 16.5 m/s with 4 m/s standard deviation
- Successful loading of a 3D GMOT with approximately 2.46×10^8 atoms

## 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 $^{87}$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 $16.5(9)$ m/s and a velocity distribution of $4(3)$ 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 $2.46(7)\times 10^8$ atoms. Methods to improve output flux are discussed.
