A group of physics students from the University of Leicester have calculated that the laser-deflecting shields used by spaceships in Star Wars are not only theoretically feasible, but could also be constructed using today's technology.

However, there are some problems that would require some creative workarounds.

The students made some simple assumptions based on watching the Star Wars movies, namely that the laser weapons used just red or green light, and the deflector shields used plasma held in place by a powerful magnetic field.
