Nested Gaussian beam dark spot trap array

1D optical lattices made by two equal, counter-propagating laser beams can only trap atoms in bright spots as there is no confinement in the radial dimensions. However, using two beams of different beam waists, the bigger beam forms a light wall around the trap sites that allows confinement of dark spot traps in all dimensions.

Here is our poster (pdf is below) on this topic from the American Physical Society (APS) Division of Atomic, Molecular, and Optical Physics (DAMOP) meeting in 2017 with more details.

Correction: All 3D plots have their axis labels switched: switch rho/w0 with z/lambda (user error...)
