Abstract

The invention relates to a fiber laser comprising a ring-shaped resonator (3). A first section of the resonator is formed by an optical fiber (7) while a second section of the resonator is formed by an optically pumped amplifier fiber (8). The fiber laser further comprises an injection point (4) for injecting light of a pump light source (1) into the resonator (3) as well as an extraction point (5) for extracting generated laser light from the resonator (3). The aim of the invention is to design a more developed fiber laser. The aim is achieved by providing the resonator (3) with at least one reflective optical component (12, 51) which reflects the laser light circulating in the resonator (3).
