Phase-controlled, fractal laser system

Abstract

In order to improve a semiconductor laser system with a plurality of semiconductor laser units, from which laser radiation exits, 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 laser radiations generated by the respective semiconductor laser units exiting from one end of this fiber bundle, the 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 it is suggested that the semiconductor laser units be designed such that they operate relative to one another in a phase-defined and frequency-defined mode operation, that the laser radiation of each semiconductor laser unit be coupled into the respective laser light-conducting fiber with low loss, that each fiber be a single-mode fiber and that in the total laser radiation the laser radiations of several, preferably all of the semiconductor laser units be controllable in their phase independently of one another.
