Creo, Which company does produce CTP laser?

That's a good question that I am not sure of the answer. I doubt that any of the companies that are selling CTP (computer to plate) equipment are actually manufacturing their own lasers. I think there must be a central manufacturer or two that is actually making lasers for them all. There are also many different lasers and laser types that are used for CTP (computer to plate) laser imaging. Does anyone know who actually makes the lasers for these guys?
