title: Large capture-range of a single-beam gradient optical trap.
abstract: We have observed long-range trapping with a single-beam gradient force optical trap. 6 to 10 microm polystyrene beads that are initially approximately 100 microm away from the trap-center can be pulled into the trap-center. Particle-tracking enables us to determine the trajectory of a bead as it moves towards the trap-center and map out a capture zone inside which trapping can occur.
