Diffusion Cooled Resonator Maintenance


This class is designed to provide classroom and hands-on instruction for the maintenance and repair of the Rofin-Sinar Diffusion Cooled Laser (DC-025, DC-030 & DC-035) as part of a CINCINNATI CL-7A and CL-707 Laser System. This course also covers inspection, cleaning and alignment of beam delivery. For training on topics outside of the laser resonator and beam delivery, please consider our Frame Maintenance Class.

  • Although programming and operation are briefly discussed in this program, we strongly recommend that you first attend the Laser Operator Class.

  • Prior experience working on the laser system with a Service Representative or a trained maintenance person is advised.

  • We highly recommend that soon after attending the maintenance class, participants complete a planned maintenance on a laser system, under the supervision of a CINCINNATI Service Representative, to review and practice what they’ve learned.


Due to machine availability, training at CINCINNATI can only be done for current model machines. Training for discontinued models must be done at the customer’s facility.
