Laser Innovations - CR Series Coherent Laser

Laser Innovations supports the Supergraphite series of lasers which are no longer supported by the manufacturer. Whether your laser is in need of repair, or you wish to upgrade to a newer system, contact us. We offer state-of-the-art ion laser system at a fraction of the cost of purchasing a new system. And we also offer older units that have been fully reconditioned for the truly economy minded.
