Power driven fractal laser system - controls individual semiconductor units to illuminate different target surface elements with different intensities

摘要

The semiconductor laser system includes several semiconductor laser units (18) each with a coupling element. The coupling elements couple the light beams of respective units (18) into light conductive fibres (20). The fibres are bundled together forming a light conductive system (10). This has one end from which a combined beam (14) from the sum of the beams generated by all the units (18) is emitted. When all units are lasing, the combined beam (14) illuminates a target surface (16) on an object to be illuminated. A control (32) definitely controls the output of each individual semiconductor unit (18). The control (32) irradiates different surface elements (30) of the target surface (16) with different intensities for each surface element (30).
