Abstract
Laser machining system () comprises a high-power laser () for generating a high-power pump laser beam (HP-MM), control signal laser () for generating a control signal laser beam (SS), an optical fiber () leading from the two lasers to a laser machining head (). The optical fiber has an SRS amplifier fiber () with an inner fiber core () of higher brilliance and with an outer fiber core () of lower brilliance surrounding the inner fiber core. The control signal laser beam (SS) is coupled into the inner fiber core and the pump laser beam (HP-MM) is coupled into the outer fiber core. The radiation component converted from the outer fiber core into the inner fiber core due to the SRS amplification is adjusted by means of the coupled-in power of the control signal laser beam (SS) to adjust the brilliance of the machining laser beam leaving the SRS amplifier fiber.
