Abstract

We simulate the dynamics of particle motion during launching and loading into optical traps to enable strategies for controlled loading of optical traps in vacuum. Particle dynamics during trap loading are simulated in air and compared to measured trajectories to validate particle behavior at measured launch velocities. The simulated dynamics are analyzed in both ballistic (vacuum) and diffusive (air) regimes to determine the forces required so that particles can be trapped stably. These results provide a foundation for developing control algorithms to reliably launch and load particles into optical traps in vacuum, and examples of controllers will be presented.
