Beams of light have the ability to move objects by transferring some of their momentum to illuminated objects. This force arises from gradients in energy density, causing small dielectric particles to be attracted towards the brightest regions of the light beam, and gradients in the phase, directing radiation pressure and pushing objects along the direction of propagation. These effects may be harnessed to move and control small objects with applications across many scientific disciplines. One special group of light beams, commonly referred to as tractor beams, can transport small objects upstream, opposite their direction of propagation. This thesis begins with a formalism for describing and predicting the forces that beams of light exert on illuminated objects in terms of the amplitudes and phases of the electric and magnetic fields in light beams. Pursuing the goal of long-range optical micromanipulation, we describe in detail the nondiffracting modes of light known as Bessel beams, and apply our understanding of optical forces to design solenoidal modes that can act as tractor beams. We introduce experimental techniques for creating the highly structured beams of light that are designed with this formalism. Finally, we report the successful creation of these modes of light over 1 meter in length in the laboratory.
