Resonant Laser Manipulation of an Atomic Beam

Theories for laser‐atom interactions have been under development since the advent of laser technology. The theories have yet to be adequately integrated into kinetic flow solvers. Realizing this integration would greatly enhance the scaling of laser‐species interactions beyond the realm of ultra‐cold atomic physics. A representative numerical investigation was conducted using a custom collisionless gas particle trajectory code, demonstrating this goal in the present study. The investigation covered neutral atomic beam steering and collimation using near‐resonant laser fields. In addition to the numerical investigation, a validating experiment was conducted. The experimental results showed good agreement with the numerical simulations when experimental parameters, such as finite laser line width, were taken into account. These simulations showed trends and some limitations associated with the use of a continuous‐wave Gaussian laser fields for the steering and collimation of a geometrically skimmed cesium a...
