Typical traps use optical fibers to guide those beams. This thesis proposes a design for the coaxial alignment of optical fibers that allows for the fibers to translate along a common axis while maintaining alignment. Additionally, this design enables the optical fibers and trapping samples to be quickly and easily swapped out for different experiments. A full optical trapping setup was constructed using this design and successfully demonstrated the trapping of multiple polystyrene microspheres.","abstract_html":"Dual beam optical traps use radiation pressure from two counterpropagating laser beams to manipulate microscopic particles.
