ABSTRACT:
In order to improve a semiconductor laser system with a plurality of semiconductor laser units comprising a laser oscillator, laser radiation exiting from each of these units, a light-conducting fiber associated with each semiconductor laser unit, a coupling element for coupling the laser radiation exiting from the respective semiconductor laser unit into the respective light-conducting fiber, and a fiber bundle comprising the fibers as light conductor system, a total laser radiation formed by the sum of the coherent laser radiation generated by the respective semiconductor laser units exiting from one end of the fiber bundle, this total laser radiation illuminating a target surface on an object to be irradiated during laser activity of all the semiconductor laser units, such that complex irradiation tasks can be performed with this system in a simple and as effective a manner as possible it is suggested that a control be provided for controlling the power of each individual semiconductor laser unit in a defined manner, and that an irradiation of different surface elements of the target surface with an intensity individually definable for each surface element be specifiable to the control.
