Abstract

A high average output power of a solid state laser is achieved by means of a temporal multiplexing method. It combines several laser beams and conserves the beam quality of each beam in the combined laser beam. The multiplexing method is demonstrated for three laser beams delivering a total laser power of 3 kW. Two concepts for the laser and multiplexer setup are realized. The first aims at an optimized beam quality whereas the second takes the demands of a flexible work tool into account. Both systems are using optical fibers for the beam delivery to the workstation. The requirements for delivering high power laser beams by optical fibers are discussed. Applications in laser beam welding of aluminum and stainless steel are shown.
