Patent ID: 8659386

Claim:
A laser system comprising: a laser fiber having a connector; and a laser device having a laser for supplying laser light, a coupler for the connector of the laser fiber for coupling laser light in the laser fiber connected to the coupler via its connector, and a controller for operating the laser depending on an identification code assigned to the laser fiber, wherein the controller compares the identification code assigned to the laser fiber with an identification code assigned to the laser device, wherein the identification code assigned to the laser device is different from identification codes assigned to other laser devices, wherein the identification code assigned to the laser device is permanently programmed into a memory of the laser device, wherein the comparison is made according to a secret algorithm stored in the laser device, and the controller only operates the laser, if the comparison has the outcome that the laser fiber is exclusively intended for the laser device and not any of the other laser devices, wherein the controller stores in the laser device a record of use of each laser fiber used in combination with the laser device under the identification code assigned to the laser fiber.
