Go to LPKF website and search for ProtoLaser. They do it.
Have a look at gabuleu.blosgpot.comI bought a Shapeoko CNC and upgraded it to have a small diode laser. Not so expensive in the end.
I believe LPKF uses a UV laser, not an IR one. You probably are using a CO2 laser which emits in the infra red (IR).
