Creating Custom Optical Potentials with Spatial Light Modulators
Abstract/Contents
- Abstract
- Modern atomic physics experiments use precisely engineered optical intensity profiles to trap and manipulate atoms. These profiles are created by optical systems based on spatial light modulators (SLMs) and acousto-optic deflectors. SLMs can, in theory, produce nearly arbitrary two-dimensional and select three-dimensional intensity profiles though technical challenges have largely limited SLMs to the formation of optical tweezer arrays. In this thesis, I present computational and experimental methods to greatly expand the set of achievable intensity profiles. For 2D profiles, finding an optimal phase distribution for the SLM is the primary challenge; I demonstrate a novel phase-smoothing approach to eliminate optical vortices and allow for better convergence. I also show results from a camera feedback procedure that corrects for aberrations not considered in the computational model. Finally, I present results from two methods of generating arrays of 3D bottle beams: spliced phase gradients and acousto-optics. These results highlight the viability of our methods for future use in neutral atom experiments.
