Louis, fascinating results, it appears. What is the profile of your light beam? How much of the area between the masses does it cover? Does it matter? Can you report on dependencies on laser intensity? How close do the masses have to get together in order to induce the amplitude of torsional motion you observe? Is there room in between? Is it imaginable to have some evacuated space between the masses to have the light not propagate through air at all between the masses?
