An extremely focused laser has a very strong electric field at its narrowest point, known as the “beam waist.” The particles are attracted to the strongest field, the center of the beam, which allows for the use of the laser to move particles around. Away from the center of the beam is higher potential, so the particles move to the lower potential in the center of the beam.
