Several companies make systems for this. Most are restricted to Class IIIA power levels for laser safety reasons. Almost All of them use much higher quality parts then in low cost laser show systems, and for good reason.
Lap Laser, Virtek, Laser Projection Technologies, Z-Laser etc.
You need a control system with a SDK to drive the scanners in the projector. Pangolin comes to mind, as does the Riya Lasers products. Ignore the people who are going to chime in any second and tell you to do this with a modified sound card. The shop floor is no place to have beam position drift and noise issues.
You want either a Diode Pumped Solid State Laser, a Helium Neon Laser, or a Single Mode diode laser, simply for the better beam quality then would be found in a average laser show projector. This means you want a small spot size, which is determined by the "Transverse Mode" of the source laser.
You also want a better grade of galvanometer scanner, ie Cambridge Technologies or Pangolin's Scannermax, maybe Nutfield products. The reason being the need for sharp, very accurate scanning with a scanner position sensor that does NOT drift.
