Abstract
A laser system includes a laser radiation source for emitting light, and an optical fiber unit that includes an optical fiber. The optical fiber includes a light guiding region, an input coupling end having a first fiber end surface for coupling the light into the light guiding region, and an output coupling end having a second fiber end surface for coupling the light out of the light guiding region. The laser system further includes a coupling device for coupling the light into the optical fiber unit, a reflection element configured to reflect the light coupled out of the light guiding region back toward the second fiber end surface to be coupled back into the light guiding region via the second fiber end surface, and a measuring device configured to capture the light reflected by the reflection element.
