Generation of Atomic Optical Lattices by Dammann Gratings

Figure 5

Intensity distribution of the array of optical trap with high density generated by Dammann grating (𝛽=0.2, 𝑁=4, 𝐾=15, 𝑃=10𝑊,  𝜆_𝑙=0.53 μm). (a) Intensity isoline of a single optical trap; (b) 2D intensity distribution of a single optical trap; (c) density distribution of the intensity for the array of optical trap (fraction); (d) 1D intensity distribution along 𝑥 direction that passes through the center of optical trap.
