To expand on Steve's comment: 3D Technology Labs did indeed demonstrate a similar technology 10 years ago. It wasn't based on plasma, though; it was based on nonlinear optical effects in a cube of specially doped glass. When two laser beams of different wavelengths intersected inside the glass, they caused the dopant atoms to emit light. I got to see it in person, and it was pretty freakin' cool.
