Abstract
The idea of exchanging angular momentum between microscopic parts and the outside world has been a key idea in many recent experiments involving nano-photonic technologies. Indeed, many experiments with optical tweezers involve the application of tailored beams with orbital angular momentum to microscopic particles. A variety of such beams can be created with modern computer-generated holograms such as spatial light modulators. However, often little consideration is given to the application of these beams after they have been generated. Here we will discuss the measurement and application of beams with orbital angular momentum under the microscope. Specifically, measurement of the applied optical torque, distortion and rotation of beams carrying OAM. Finally, we will discuss the application of vortices in topological insulators.
