Abstract
A laser alignment system is used to align an output fiber with a fiber laser, for example, when coupling a feeding fiber to a process fiber using a beam coupler or switch. The alignment system includes a laser alignment apparatus that is coupled at a first end to the output fiber and at a second end to a beam dump/power meter. The alignment apparatus defines a light passage and a light capture chamber along the light passage. When light is not aligned into the core of the output fiber, at least a portion of the light passing out of the output fiber will be captured by the light capture chamber and detected by a photodetector in optical communication with the light capture chamber. By monitoring the readings of the photodetector, the output fiber may be properly aligned with the laser light from the fiber laser.
