Laser radiation source of high power density and high energy for material treatment

摘要

Laser radiation source for material treatment with an optical unit for the shaping of the laser beam on a working surface,characterized by the,that a plurality of diode-pumped fiber laser (2), whose energy is controlled individually, are provided,that the outputs of the fiber laser (2) by means of terminating pieces (26, 94) with an optical unit (8) are connected to the shaping of the laser beam,the outputs of the closure pieces in a first part and the optical unit in the first part and in a second portion of a multi-part receptacle are arranged,the optical unit (8) has a modulation unit, on the input of which the output beams of the individual fiber laser (2) and are directed in each case by means of which the individual laser beams are modulated,the laser beams emerging from the modulation unit by means of the optical unit (8) are combined and are grouped together so that the jets onto the working surface (81) impact,the optical unit (8) for shaping of the laser beam a transmission unit for the transmission of the emerging from the end caps..
