Not from light as in visible light, but from high energy gamma-ray photon interactions - with other photons or matter:
Visible light is composed of photons. Photons do not have mass but they do have energy and momentum. Einstein's equation E = mc^2 may suggest energy and mass are interchangeable and one can be converted into the other. So because light has energy perhaps it could be converted into mass somehow.
The amount of matter converted to "light" in the Hiroshima Bomb was about the mass of a large pencil eraser. About 20 kilotons per gram of matter converted, is the commonly stated standard for ordinary fission.
The direct back-conversion is obviously possible, in theory - the applications would appear to be limited, at first glance.
The creation of matter/antimatter pairs offers a work-around of the brute force limitations - with its own problems, though. Intriguing what the applications would be.
I wonder if creating future technology that can create matter from energy could be used in some sort of 3D printing application. Perhaps items made of matter or antimatter could be made to materialize into existence out of stored or created energy, almost instantly, or over time, somehow using this imaginary futuristic technology.
If we could capture energy from the sun or interstellar space and convert it efficiently into matter perhaps we could ensure a steady supply or resources for future generations as we colonize space.
