How do you increase the orbital angular momentum of light?
If you are talking about the orbital angular momentum of light, then that is a very simple concept. If one has sufficient energy at their disposal, they should simply have to shine a light on it at an angle and spin the object in question around that light. This would impart energy onto the rotating object from its surroundings.
If that object is in motion, then it would continue to rotate due to conservation of angular momentum. You should have a rotating system put together by simply spinning the light and moving the object around it.
In order to move the object, you would need to have a rotating system with at least one axis that is fixed relative to your surroundings. For example, if you were using an inertial frame of reference and spinning around two axes that are perpendicular to each other, then you could spin the light around one axis while moving it around the second.
As for how you would use this system to increase the orbital angular momentum of light, I am not exactly sure. Perhaps if you were rotating around the object in a way that it is perpendicular to the direction of travel, then it should be able to impart energy onto its surroundings.
If you spin around the orbital axis of a particle that has translational velocity, then it should impart energy onto its surroundings. It is not impossible for this to increase the speed at which light is traveling.
If you are spinning around the light in such a way that it is perpendicular to its direction of travel, then it should be able to impart energy onto its surroundings. The only tricky part about this would be figuring out how much momentum and angular momentum you need to impart onto the particle.
