This chapter describes the experimental setup. The particle is trapped in a one-dimensional optical lattice formed by retroreflecting a focused laser beam, enabling strong confinement along the optical axis. The experimental system is housed in a vacuum chamber. A high-numerical-aperture lens collects light scattered from the particle, and its position is measured via photodetectors. To enable experiments with neutral particles, the system includes a charge neutralization protocol using UV light. In addition, methods for measuring heating rates and characterizing trapped particles are detailed. The feedback control system extracts the particle’s motion from photodetector signals using high-pass and low-pass filters. These signals are used to modulate the feedback force, realizing cold damping in all translational and rotational degrees of freedom. The system also allows synchronized switching of the trapping beam and feedback cooling. This capability is essential for time-of-flight measurements.
