Description
We develop a two-dimensional bottle beam array for laser trapping atoms in the ground and Rydberg states. A dipole-trap laser beam is diffracted by a phase spatial light modulator imprinted with a phase pattern to generate a 6 by 6 array of the bottled beam. The beam arrays are then focused by an aspheric lens and imaged by a CCD camera. The distance between two nearest-neighbour atoms is 396 𝝁m, and the diameter of the ring of intensity peak for each trapping site is 82 𝝁m. The average similarity of the intensity distribution between the measured trapping sites and the numerical calculation is 86%. This trap system opens appealing applications in quantum information processing and simulation based on Rydberg atoms.
