Abstract
A fiber laser system includes a fiber laser connector having a housing to terminate a fiber that generates a laser beam. A chamber extends internally along a length of the housing. A light trap includes a plurality of threads formed along a wall of the chamber to trap light reflected back to the fiber laser connector in response to an application of the laser beam to a workpiece.
Claims20
A system, comprising:
- a fiber connector including a housing, the housing including a first section to terminate a fiber to generate a laser beam and a second different section to encase at least a portion of the fiber;
- a chamber extending internally along a length of the second section of the housing, wherein a wall of the chamber is optically non-transmissive;
- and
- a light trap including plurality of threads formed along the wall of the chamber to trap light reflected back to the fiber connector in response to an application of the laser beam to a workpiece.

A fiber laser assembly to couple to a lasing device, the fiber laser assembly comprising:
- a pump source;
- a fiber having a first end coupled to the pump source, wherein a portion of the fiber is configured to generate a laser beam from pump light of the pump source;
- a fiber connector to receive a second end of the fiber, the fiber connector to mate with a receptacle of the lasing device, the fiber connector including:
- a housing including a section to enclose at least a portion of the second end of the fiber;
- a chamber extending internally along a length of the section of the housing, wherein a wall of the chamber is optically non-transmissive;
- and
- a plurality of threads formed along the wall of the chamber to trap light reflected back to the fiber connector in response to delivery of the laser beam.
4 more elements
A method, comprising:
- forming a plurality of threads along an optically non-transmissive wall of a chamber in a housing of a fiber laser connector;
- generating a laser beam with a fiber laser terminated by the fiber laser connector;
- receiving, at the fiber laser connector, light rays reflected back from application of the laser beam to a workpiece;
- and
- trapping each of the light rays multiple times within the chamber using at least some of the plurality of threads.
